Well .. I slept with your mother!

[bjambjam]

Two guys are sitting on a bar stool. One starts to insult the other.
He screams, “Oh ya .. well, I slept with your mother!”
The bar gets quiet as everyone listens for a reply ... but nothing.
So the first guy yells again, “Your mother gave me head twice this morning!”
Finally the other had enough and says, “Go home dad you’re drunk.”
