Pick Up Line?
If you have ever been in a bar, you know the bartender is always washing glasses, their hands are always wet. Consequently, when I ordered and paid for a drink, the change (which included several dollar bills) was all wet.
I kind of liked the bartender and was flirting and kidding around with him. The next time I ordered and was going to pay for my drink, I said jokingly, "This money is all wet, is it still good"?
He said, "Would you be good if you were wet"?
