TWO BIKERS IN A BAR JOKE
Two bikers walked into a bar. Each one orders two whiskeys and immediately downs them. They motion to the bartender, order two more apiece, and those two disappear. Again they summon the barkeep for another round. As soon as the shot glasses are placed on the bar, one of the tramps hoists his drink, turns to the other, and says: "Cheers."
The other biker growls: "Hey, asshole, did you come here to bullshit, or did you come here to drink?"
