The Jar in the Bar

So a man goes out to meet his buddies at a new bar. When he arrives, the first thing he sees is a giant glass jar in the far corner of the room, 7 feet by 6 feet, packed to the brim with $10 bills.

He sits down and asks his buddies, "What's with the jar?"
"No idea" responds his friend, so the man asks the bartender.
In his thick Irish accent, "Ah, ye warnt a know bout the haus game does yer? That'll be $10."

Annoyed but intrigued, the man pulls out a $10 and lays it on the bar, and the old man begins, "To win all the money in that there jar, I have a gallon jug of tequila ya hafta take all down at one go and not flinch or make a face," then he points to the back door, "I have a pit bull chained out back with an aching tooth ya gotta pull, but watch out, she's mean as a blarney so be careful, and at last, I gots a 90 year old lass upstairs, who's never had an orgasm in her life. You gotta go up there and make things right for her."

The man stands, shakes his head as he returns the table. "I understand!" yells the bartender, "But yer $10 stays in the jar."

So the guy get into a bit of a drinking session with his buddies, but can't stop thinking about the jar. If he could suck it up, just for one night, he could change his life.

Finally, with enough liquid courage, he stumbles up the the bar and slams down a $10 bill. "Gimme the tequila." The bartender hands him the jug and he throws it back as hard as he can, throats burning, tears rolling down his face, he finishes every drop and slams it down, without making a face. The bartender points to the door, now the man staggers through the backdoor, and the barking ensues, trash cans are crashing, there's a loud scream then silence. "Awh geez says the bartender, they fuckin' killed each other." As he shoos the crowd back he gets to the door, the man bursts thru, shirt shredded, bloodied and bruised, he shouts, "Alright, now where's the old lady with the sore tooth?!"
