Sheldon: Perhaps Howard meant passive-aggressive like asking our group to help on your project, and then only choosing Leonard.
Raj: Look, I'm sorry I hurt your feelings, but you do have strong personalities and always end up taking over.
Howard: It's not always.
Leonard: What about when we went to Comic-Con and dressed like Jabba the Hutt? You got to be Jabba's head, and I got to be his fat slug butt.
Sheldon: We looked great.
Leonard: You let a guy sit on me.
Howard: He was dressed as Princess Leia. It made a nice picture.
