Eric: Kelso, I need to use your bathroom.
Kelso: [opens door] Nope. There's nobody here. Of course, I can't see people who don't have parties for their friends. So maybe there is somebody here, and I just can't see 'em. I can't see you, Eric!
Eric: Kelso, I really need to use the bathroom.
Fez: Well, maybe you should have thought of that before you kicked us out of Donna's house, you party pooper.
Kelso: Yeah.
Fez: No party, no pooper!
Kelso: Nice.
Fez: Yeah, it really was. No party, no pooper!
