From one of the greatest comedians of all time:
"Oh I told a guy, kids today, the way they dress you can’t tell boys from girls. I was looking at one kid, I said, what is that a boy or a girl? He said, that’s a boy. I said, sure you knew, you’re his father. He said, I’m not his father, I’m his mother."
