Worst Pick-up line: ANY pick-up line.
Many women are smart enough to realize you're using a line and, even if they talk to you, you've already made a bad first impression.
Just be yourself.
I don't really agree with that. Some lines are funny, and even though it's obvious that it's just a "line" if it makes me laugh, you've broken the ice and shown me that you have a good (or decent) sense of humor. Now obviously, if it makes me roll my eyes or frown up my face, you've made a bad impression. But I've heard some really funny ones that made me genuinely smile even if I wasn't really interested - and to me, that's not a bad thing.

On subject... over the weekend, I went to a Burger King and this very handsome, but very old guy (probably in his late 60s or so) said to me, "what are you, like 20?" With this thread in mind, I laughed and said, "are you serious? That's the best you could come up with?" And we both laughed.
Then when I got ready to leave, he said, "for real, little lady, how old are you 22? 25? I like 'em young!"
I laughed because he was old and SO lame... but that really grossed me out.
