A guy goes into a bar and orders a drink, shoots it down and orders another, shoots it down and orders another

The bartender says "Hey, buddy, I don't know what's bugging you but getting drunk is not the answer."

The guy replies "Oh yeah? Well, I just walked into my house and found my wife in bed with my best friend."

Bartender says "Boy that's pretty bad...what did you say to your wife?"

The guys replies "I told her to pack her bags and get the hell out and I never wanted to see her again."

Bartender says "Well, that seems reasonable, what did you say to your best friend?"

The guy replies "Well, I looked him straight in the eye and said 'Bad dog! Bad dog!"
