I was watching the season 3 DVD (thank you birthday!), the episode "The Thin White Line".
Person at rehab clinic: What's your name?
Peter: um... (sees a pea) Pea... (sees someone cry) tear... (sees a gryphin fly across the room) gryphin. Peter Griffin! Ah crap.
And from the Bachelorette episode:
Bachelorette: Will you take this rose?
Quagmire: You mean after I drugged you and tried to have sex with your unconcious body?
