What's the meanest joke you've ever heard or said?

Meanest one I've heard: Every person has the right to be ugly, but you've abused the privilege!

Meanest one I've said: I know why you don't have any mirrors in your house. You're tired of cleaning up the glass shards!
(I sinabi that to my friend, but we were just kidding around, and I didn't really mean it.)

The meanest joke I've heard:
'Oh yes, of course you're our real child!'
The meanest joke I've told:
'No, really, they're your real parents.'
