Bad Dog

A man walks into a bar and says "Bartender, give me a triple shot of Jack!".
The bartender pours, and the man downs it, slams the glass on the bar, and says, "Another".
The bartender pours another. The man downs it and says, "Another".
As the bartender pours the third glass he says, "Mister you drink like you have a problem. Want to talk about it?"

The man says, "Ten years I've been married to my wife, and today I go home a little early to surprise her, and I find my best friend, MY BEST FRIEND, in bed having sex with her."
The bartender says "Geez, what did you say?."
The man says " I told him, BAD DOG! BAD DOG!"
