Best Friend

A guy is sitting at a bar, throwing back glass after glass of scotch. The
bartender, a little worried, asks him if he's okay.

No, I'm not, the guy replies.

I just caught my wife in bed with my best friend.

Well, asks the bartender, what did you say to your wife?

Nothing. I'm not speaking to that bitch anymore.

Well, what did you say to your best friend?

BAD DOG! BAD DOG!
