I love everyone who quoted The Emperor's New Groove, one of my all-times favorites. ("Why do we even HAVE that lever?") My 3 year old was sitting in a high chair in a restaurant and he grabbed a menu, pretended to read it and said "Is there anything on this menu that isn't swimming in gravy???" We just about died laughing and are still quoting that movie to this day.
Another of my favorite quotable movies is 16 Candles.
"Dong is here for five hours and he has somebody. I'm here all my life and I'm like a disease."
"He's wearing a red sweater, tan trousers and argyle socks. No, he's not retarded!"
"Games, Jake, silly torturous games. Any half-good looking chick can rob me blind 'cause I'm too torqued up to say no."
"That's why they call them crushes. If they didn't hurt, they'd call them something else."
"I've had guys love me before, but never for six months in a row."
"I bet the guys who thought we had to get married are feeling pretty stupid right now, eh padre?"
There are so many more great lines. I love that movie!
