Three guys are drinking in a bar when a drunk comes in, staggers up to them and points at the guy in the middle.
"Your mom's the best lay in town"
Everyone expected a fight, but the guy ignored him, and the drunk wanders off.
Ten minutes later the drunk comes back and points at the same guy.
"I just screwed your mom and it was SWEEEEET dude"
Again the guy refuses to take the bait and the drunk wonders off.
Ten minutes later the drunk comes back.
"Your mom even let me..."
Finally, the guy interrupts: "Go home Dad, your drunk"
