I never heard any, but I say some myself - "Baby if I was a tire I would roll over you" (sounds humorous on my language) | and there's this one I use which I saw on the Internet and really works to get some laughs - Baby you turn my floppy disk into a hard drive!
Haha. I've heard some pretty funny pick up lines. Last summer I was on a Carribean cruise in Nassau. I was walking along the shore when this really good-looking guy approached me. Before he even asked me my name, he was like Damn girl! If you were a fruit, you'd be FINE apple.. I must say it really made me laugh out loud too. Lol
