A man walks into a bar...
...and sees a sign: "Free Beer For Life If You Can Pass Our Test!"
He asks the bartender, "What's this 'test'?"
The bartender says, "First, you chug a gallon of pepper tequila. Next, you go out back and pull the sore tooth out of our alligator's jaw. Finally, there's a girl upstairs who's never slept with a man, and you gotta make things right with her."
The man exclaims, "That's a piece of cake! Alright, let's do this." The bartender hands him a gallon of pepper tequila, and the man struggles to chug it. He manages to finish, and he slams the bottle on the counter, but he's teary-eyed and nearly fainting. The bartender warily points him in the direction of the alligator.
After several minutes of screaming and growling and ungodly ruckus, the man stumbles back in. His shirt is torn, and he's bleeding profusely. He can barely stand up, but he aims a glassy stare at the bartender and says, "OK, where's the girl with the sore tooth?"
