A man walks into a bar and sees a sign that says, "Free drinks for life if you can pass our challenge." Intrigued, he decides to give it a shot and asks the bartender what the challenge is.
The bartender explains, "You have to successfully complete three tasks in a row. First, you have to drink a gallon of beer without stopping. Second, there's a rabid pit bull in the back room with a sore tooth that you have to pull out. And third, there's a 90-year-old woman upstairs who has never experienced pleasure in her life, and you have to give her multiple orgasms."
The man thinks for a moment and then decides to give it a go. He chugs the gallon of beer in record time and heads to the back room to face the pit bull. The patrons in the bar hear growling, barking, and the man screaming in pain. Eventually, the door opens and the man emerges, bloodied and bruised, but victorious.
He then heads upstairs to attend to the 90-year-old woman. Again, the patrons hear loud noises, moans of pleasure, and the woman screaming in ecstasy. After what feels like an eternity, the man comes back downstairs, exhausted but with a satisfied smile on his face.
The bartender is amazed and asks, "How did you do it?!"
The man chuckles and replies, "Well, the gallon of beer wasn't easy, and pulling that tooth out of the pit bull was definitely a challenge. But giving that 90-year-old woman multiple orgasms was the hardest part."
The bartender looks puzzled and asks, "Why was that the hardest part?"
The man grins and says, "Because I had to stop halfway through to catch my breath, and by the time I finished, the pit bull had bit my leg and I had to wrestle him off the old lady!"
