That reminds me of a joke we had when we were kids:
There's this kid who walks home from school and every day he sees the same prostitute standing on the corner. Each time she waves at him and says "Hello little one" and waves her pinky. Eventually the kid gets up enough courage and approaches her and asks "Why do you keep waving your pinky at me?". The lady says "Because that's the size of your penis"
The kid walks off. Next day he's walking home from school and sure enough the same prostitute waves her pinky and says "hello little one". The kid turns around, sticks both his hands in his mouth and forces his mouth open as wides as possible and says "Hello lady"
