Best and worst pickup lines!

I was on my lunch break, over at the hospital when a guy approaches me, "hi Mrs I see you come in here everyday and I was wondering If you would like to go get a coffee sometime?" "well I appreciate the offer but I don't think its a good idea" "why not, I'm a good guy?" "I never said you weren't, just I'm gay and I don't want to give you the wrong impression" "you aren't gay, your just in a phase, I'm positive If you had a guy like me you would never need a girl" "If you say so,goodbye" I don't know how many times I've been told that. Well this just made me think, what's the wrost pickup line that you have ever heard, and what's the best or even the worst and best that you have used?
