That's one of my favorite episodes, where he got the DNA of Leonard Nimoy. There sort of is. It's a flashback episode where Leonard moves into Sheldon's apartment for the first time, after applying for roommate at the university. He met Raj and Howard at the uni. I think it's called "The Staircase Implementation".

They promoted Leslie to main character forward while, but afterwards they couldn't think of what to do with her so she became a minor character again. The way Sheldon's insults are so pathetic is really funny. Yeah, there's also a minor gag where Sheldon keeps changing the wifi password to kick Penny off when she's using it.
