A guy walks into a bar and orders a triple scotch and drinks it in one gulp.

The bartender says, "Boy, something sure must be wrong with you."

"Yeah," the guy says, "I caught my best friend fucking my wife. I told her to pack her shit and get the fuck out."

"What did you tell your best friend?" Asked the bartender.

To which the guy replies, "I looked him straight in the eyes and said, Bad Dog."
