A guy walks into a bar and orders a triple scotch.

The bartender pours him the drink and the guy downs it in one gulp.
"Wow", says the bartender,
"Something bad must have happened."

"Yeah it did," he said.
"I came home early today, went up to the bedroom, and found my wife having sex with my best friend."

The bartender pours the guy another triple shot.
"This one's on the house".

The dude gulps it down once again.
The bartender asks
"Did you say anything to your wife?

The guy answers
"Yea, I walked up to her, told her to pack her bags and get out!"

"What about your friend?" asks the bartender.

"I looked him straight in the eye and said BAD DOG."
