What is the stupidest pick up line you have ever heard?

A couple of weeks ago I was at Gold Country Casino, and this guy came up to me and said, "can I ask you a question?" I said, "Okay." He said, "have you ever seen a dime screwen a nickle?" I said, "No, I can't say that I have." So he opens his hand and in it he has a dime, screw and a nickel. lol How stupid is that? lol But it did make me laugh.
