A man is sitting at the bar in his local tavern, imbibing a few shots of whiskey. One of his friends happens to come into the bar and sees him.

"Lou," 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."

He then throws back another shot of whisky in one gulp.

"But," says the other man, "I'm your best friend!"

The man turns to his friend, looks at him, smiles, and then says,
"Not anymore! He is!"
