A fellow walks into a bar, and his eye is quickly drawn to a large
glass bowl filled with ten dollar bills. Intrigued, he asks the
bartender why the bowl is there. The bartender explains that it's an ongoing challenge at this particular bar.

"For ten bucks you get a shot at three tasks --- if you complete them
all successfully, you'll get yer ten bucks back, along with the rest
of the money."

The fellow expresses an interest in the idea.

"Well," says the bartender, "it sounds a lot easier than it really is.
A lot of guys haven't been able to hack it. You gotta drink a whole
one of those kegs in the corner over there --- then there's this crazy
mad pit bull out back, through that door --- he's crazy on account of
he's got an infected tooth, so you'll have to pull that."

Some of the regulars start to pay attention to the guy, so he inflates
his chest and prods the bartender on.

"Well," says the bartender, "then you gotta --- upstairs is the lady who owns this place -- she's pretty old, but you gotta --- well, you gotta make her finish if you know what I mean."

Without hesitation, the guy proudly places a new ten dollar bill into
the bowl, and sets off to the nearest keg in the corner. The regulars
stare on, having seen many men fail.

After successfully draining the keg in record time, the man makes his
way out the back door, surprisingly staggering very little. For a good
half hour, painful sounds of growling and crashing come through the
wall as the regulars shoot knowing looks in each other's directions.

As the clamor outside subsides, and the bartender starts to add ten to the running total cash pot, the fellow staggers in through the back door, bloody, clothing in shreds, with a determined look in his eye.
The others look on in amazement as he claps his hands together and says, "Alright, now where's that ugly old lady needs her fuckin' tooth pulled?"
