Three guys are drinking in a bar when a drunk comes in, staggers up
to them, and
points at the guy in the middle, shouting, "Your mom's the best
sex in town!"
Everyone expects a fight, but the guy ignores him, so the drunk
wanders off and
bellies up to the bar at the far end. Ten minutes later, the drunk
comes back,
points at the same guy, and says, "I just did your mom, and it
was sw-e-et!"
Again the guy refuses to take the bait, and the drunk goes back to
the far end
of the bar. Ten minutes later, he comes back and announces,
"Your mom liked it!"
Finally the guy interrupts. "Go home, Dad, you're
drunk!"
