Apart from the episodes you listed:

Hurl and Go Seek: I don't like watching a bunch of people slowly becoming sick in many disgusting steps that lead up to it. The fact that Shawn is paranoid that they are zombies makes it all the more disturbing. And they just had to end it with Jasmine puking on everyone.

You Regatta Be Kidding Me: Here's what can be known about this episode: It features:


 * Zoey self-harming herself just to figure out who Mike is.

The Bold and the Booty-ful is also a disturbing episode, mostly for Gwen drawing excrement on Chris' face.
 * Cameron grabbing Scott and nearly murdering him.
 * Duncan's weird line "Beautiful... just beautiful." This is disturbing because Duncan has now lost his mind. He has been built up in the season to slowly become heroic. But instead of giving into it, Duncan doesn't let go of villainy and destroys private property. And then, he gets arrested... unexpected is the complimentary word for this.

Brunch of Disgustingness is a classical disturbing episode. I love watching it because you never know how much farther its sicknes can go. It's the most iconic episode that Cartoon Network censored or dubbed over, and for obvious reasons.
