Bartender looks down to the end of the bar and sees a guy with his head down who hasnt touched his drink for over a half an hour. He heads over to talk to him. Hey pal, is something wrong?

Yeah,… Im really depressed

Why, whats the matter?

I caught my wife in bed with my best friend

Wow, thats horrible. What did you do?

I kicked her out of the house, sent her packing its over

Thats pretty drastic, what did you do to your best friend?

I sat him down… tied him up… looked him straight in the eye… and said… Bad Dog! Bad Dog!
