One Million Bucks, B.C.

'''Chris turns back the clock to the stone age as the castmates engage in prehistoric challenges. One castmate alters the game with her personal digital assistant and personal rules, making another player adjust to his presence, as another goes to drastic measures in order to get what she wants.'''

Plot
The episode opens inside the girls' trailer, with Heather angry that Lindsay has hair, while she hasn't. This is made even worse by the fact that it was Lindsay's fault that she ended up bald in the first place. After Lindsay complains about a knot in her hair, Heather volunteers to solve the problem and pulls particularly hard on Lindsay's hair with a hairbrush. Heather is now extremely desperate for hair, but she believes she is too smart for "Lindsay blonde" and doesn't want "Leshawna's gross weave" or "Beth's pathetic ponytail". When Courtney enters, Lindsay glares at her, since now that Courtney is on the team, no one will listen to her anymore. Upon seeing Courtney's hair, Heather tells Courtney that it's great to have her "hair", but corrects herself with "here". In the guys' trailer, Justin talks about all the parts of his body his agent tells him to protect while Duncan talks about how he doesn't care about Courtney anymore (while secretly daydreaming about her).

The teams hear a loud foghorn and exit their trailers to find Chef and Chris outside in loincloths. After Chris tells the castmates about a set of special treatments Courtney gets for herself, such as keeping her personal digital assistant, having her own bathroom, and dining on gourmet food due to her winning her lawsuit, he announces the challenge to be about a period movie. Beth then thinks that the period will be the 1800's, but it is actually the Paleolithic period, a.k.a The Stone Age. Chris then tells the castmates to dress up in loincloths and gives Heather a Flintstones-like wig.

The first challenge involves both teams trying to make fire with only rocks. Chris instructs them to go search for firewood, and while they're all searching, Chef roughs up Duncan and makes him get rid of all the non-prehistoric objects he tried to smuggle into the challenge. However, they're interrupted by Harold getting chased around by woolly beavers and Duncan uses this moment of diversion to palm something without any other contestant, Chef, or Chris noticing. While Lindsay argues with Courtney about no one listening to her since she arrived, Duncan steals glances at Courtney. When the challenge begins, Duncan and Courtney start a competition between each other to see who can light the fire faster. Duncan ultimately wins using the item Chef failed to confiscate, his lighter, to light the fire. After Courtney complains about how the rocks couldn't light anything, Lindsay then lights a fire accidentally, with only one strike of the rocks. The second and final challenge involves two members of opposite teams in two rock pedestals above a tar pit, trying to knock each other off with bones. Chris then reveals that since he saw Duncan using the lighter to set up the fire, the Grips won the first challenge and they get larger bones to fight with. The first round is between Lindsay and Leshawna. After Lindsay asks when the fight begins, Chris blows on the giant bighorn from the beginning of the episode, startling Lindsay and making her fall into the tar pit. In the second round, Heather fights against Beth. While Heather throws random strikes, a giant Monster Loon snatches her new wig and makes her fall forward and she clings onto Beth's bone. Beth lets go and Heather falls into the tar pit. The next round is between Harold and Justin. When the fight begins, the Woolly Beavers return and chew through Harold's rock pedestal, as if it were a piece of tree trunk, making him fall forward and pull Justin off his pedestal, causing both to fall into the tar.

With the score tied at two apiece, Chris then proceeds to announce the final tie-breaker bout, Courtney vs. Duncan. Since the Woolly Beavers destroyed one of the pedestals, Courtney and Duncan must now share one. While on top of the pedestal, Courtney clings onto Duncan so as not to fall. After Duncan teases her about her wanting to kiss him, they both fall backwards, but Courtney grabs onto Duncan's arm and pulls them back up and they accidentally kiss. After a confessional where both reveal that they still love each other, but at the same time make each other angry, the pedestal is shown again. This time, Courtney pulls Duncan into an almost kiss, but before they can, she hits Duncan in the crotch with the battle bone and knocks him off the pedestal, giving the Killer Grips the win.

Chris then announces that no one gets voted off since it was a reward challenge. The Grips get a special reward; a giant Flintstones-like Mammoth rib, which Chef later accidentally knocks into the tar pit. As a consolation price, the Gaffers get a Giant Loon Egg to make a tart let. When the Giant Loon comes back for its egg, Heather beats it up and gets her wig back. The episode ends with Courtney in the confessional saying that she still likes Duncan, but will not admit it, while saying that he got what he had coming for the relationship she believes he had with Gwen. Later, Duncan says he didn't have a relationship with Gwen and that he still likes Courtney while complaining about how she hit his groin.

Chris gets the last word in confessions, apologizing for the lack of plot development regarding Heather stealing Courtney's hair, explaining that due to Courtney's litigious nature; they "Can't harm a hair on her head".

Exclusive Clip
Heather, covered in tar, complains about how she thinks reward challenges are "such a waste of time", and that she really needs a makeover. She then excitedly pulls out the lock of hair she stole from Courtney earlier and sticks it to her head. However, a cameraman comes into the confessional and wrestles the hair from Heather. After he leaves, Heather sticks on her red wig. She then realizes that the wig will not come off, and is excited because she finally has "hair".

Justin: ...or maybe it's my eyes... Duncan: I mean, I did notice... back when I cared...but not now... Harold: Nice try.

Beth: What?! That's so not fair! I'm the one with a boyfriend! Chris: Care to take that up with our legal department, Beth? (Chef breaks a court mallet and Beth gasps) Chris: Didn't think so... Rule Two. Where as contestants shall continue to receive allocated meals provided by Chef Hatchet, Courtney shall be entitled to a gourmet dining experience consisting of producers, and myself as applicable. I hope you like lobster. Beth and Heather: No way! (Everyone, but Chris and Courtney yell in protest) Chris: Let's see your lawyers get you out of this one. Courtney: What?! I'm still sleeping in the girl's trailer! Chris: Where she will have a pure goose down pillow, extra comfy loftier, and 700-count sheet. Oh, and her Own... Private... Bathroom!

Courtney: I could kick your two-timing butt with my eyes closed and both hands tied behind my back! Duncan: Gonna be pretty tough to eat lobster like that! (Both growl at each other) Heather: You let go! Beth: Okay! (Lets go of Heather). Justin: (in confessional make-up room, covered in tar) I'm gonna win the million, but that shot of me standing atop the stone column is worth even more. It's gonna be an iconic File for the series. Hey, Lindsay was right about the tar, my skin does look even better. Duncan: (to Harold) Just don't go and lose this challenge for us, beavers can't swim through tar! (the beavers swim through tar)  Harold: Their teeth are the size of railway spikes! Leshawna: You'll be okay, baby. Duncan: Don't be a wimp! The columns are plaster, not wood, and beavers can't climb! (one beaver eats the stand, the other starts to climb) I guess my knowledge of prehistoric beavers is a little rusty. Harold: Down beavers, down! Get back to your dam! (falls) Woaahhh! Courtney: Don't get too hyped, Duncan won't last more than two seconds. Courtney: All you're going to kiss is the end of my bone! Courtney: Sure, Duncan has this primal animal magnetism, but he also makes me want to hit him where it hurts! Duncan: (squeaks in pain) Why do they always go for the kiwis? Why!!!? Chris: (picks his teeth) I know everyone wanted to see Heather cut off Courtney's hair. Trust me, so did I. (sips from Mr. Coconut) But, the girl's got a kick-butt lawyer, can't harm a hair on her head. (continues to pick his teeth) See ya next time, kiddies!

General

 * The loincloths used in this challenge were later used in the beginning of 2008: A Space Owen, due to Chris needing a high budget for the space-themed challenges.
