A Biker walks into a bar, he takes a seat at the bar and growls: "Bartender! Get me a drink!" The bartender obliges, and the biker scarfs down the drink. Slamming the glass down on the bar, he growls: "Bartender! Get me another!" The bartender pours him another drink. After a few more rounds, the bartender attempts some conversation: "Sir, he says, it seems that you're visibly upset. What's the problem?" The biker looks at him and snorts: "I just went home and caught my ol' lady screwing my best friend!" "Oh man," says the bartender, that's rough. "What did you do?" The biker says: "Well, I grabbed her by the hair, threw her out nekkid, threw her clothes out after her, and told her never ever to come back." "Wow," says the bartender in awe: "That's tough man, what did you do to your friend?" "Well," says the biker, "I marched right back upstairs, I grabbed him by the scruff of the neck, and I said: BAD DOG."
