Mordecai: Wait, wait, wait. Yo, Rigby. What does this remind you of? Rigby: What? Mordecai: Your 7th-grade science project on which pizza box makes the best pillow! Eileen: What? Rigby: Dude, I made ground-breaking discoveries with that project. Margaret: Come on, Rigby. We've all done embarrassing stuff. You know, when I was a kid, I used to peel the pepperoni of a pizza and eat it separately. (laughs) Geez. Mordecai: Mmm, ok? Eileen: That's not really that embarrassing, Margaret. I mean, if you want embarrassing, there's this manifesto I wrote in 6th grade. Wait, I think I still have it.
