IMHO,my FAVORITE is from "Dog Day Afternoon"
Al Pacino is trying to negotiate a hostage situation with a NYPD police negotiator, and after listening to the policemans' "promises" to get Al out of his situation, his reply to the negotiator is:
Pacino:"Kiss Me !!"
Policeman:"What?"
Pacino:"Kiss me!!"
Policeman:"Why?"
Pacino:" I like to be kissed,WHILE I'M BEING F**KED !!"
....and EVERYTIME I get in a situation where I think I'm being "taken advantage of", I reply with the "Kiss me !!"
line....
"This was no boating accident!"
