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."
