A straight-laced man
is sitting at the bar, buying rounds of whiskey and obviously
having a good time. His good friend is walking past the bar and
sees him in the window, and comes inside.
"Jim," says the shocked friend,
"What are you doing? I've known you for over fifteen years,
and I've never seen you take a drink before. What's going
on?"
Without even taking his eyes off his newly
filled shot glass, the man replies, "My wife just ran off
with my best friend."
"But," says the other man,
"I'm your best friend!"
The man pats his old friend on the back
and says, "Not anymore!"
