Really Bad Day

A guy walks into a bar and orders 6 shooters. The bartender says, "Looks like you are having a bad day."
The guy says, "Am I ever! To start, I woke up late for work. On my way to work I got in an accident. When I got to work I was four hours late, so the boss fired me. Then to top everything off I came home to my wife screwing my best friend."
The bartender says, "What did you say to your wife?"
The guy says, "I told her to get out, and I never want to see her again."
The bartender says, "What did you say to your best friend?"
The guy says, "I said BAD DOG!"
