so a guy is having drinks at a bar.

After a while he looks over and sees a huge jar stuffed to the brim with 20 dollar bills. He asks the bar tender " hey whats with the jar? Theres gotta be at least 4 grand in there?" to which the bar tender replies " oh, you wouldn't wanna know. Its just a running bet"
The guy says " try me. I love bets"
So the bar tender explains, " well first you gotta leave a $20 in the jar." Then he points to a tall man in the corner. He's 6'2" with the biggest muscles in the bar. The bartenders says " once you leave the $20 you gotta walk to lenny over there and knock him out cold. After that, you gotta go out into the alley. Theres a real old pit bull with a bad tooth. you're gonna have to do him a favour and pull the tooth. After that the last thing you gotta do is head up stairs. We have a very old prostitute named patty in her 80's and you have to pleasure her completely like shes never been pleasured before. Once you do all that, you win the jar."
The guy just laughs, " wow that's fuckin crazy. I cant believe you have had that many people attempt this before." He chuckles to himself and goes back to his beer. After a few hours and one too many drinks, the guy looks over at lenny thinks " that guy isn't even that tall or buff. I could deck him. Besides what's the worse that could happen?" drunkenly he chugs his beer and walks over to lenny. The guy makes one clean punch to lennys face and lenny falls to the floor knocked out cold. At this point the bar is silent now. Everyone is watching the guy.
The guy starts heading for the back door and grabs a drink out of someone's hand, chugs it and tosses the glass. Then continues to head to the back alley.
Everyone in the bar is still silent and all they can hear is the roughest fight coming from the alley way. There's a cacophony of screaming and howling that goes on for nearly half an hour. Suddenly it stops. The drunk guy stumbles in, covered in blood and sweat. His clothes are disheveled and torn here and there. He drunkenly limps to the bar tender and says " alright man, Wheres that hooker with a bad tooth?"
