A man walks into a bar and sees a sign that reads, "Free beer for a year for whoever can pass the challenge." Intrigued, he asks the bartender about the challenge.
The bartender explains, "You have to complete three tasks in order to win the free beer for a year."
The man agrees to the challenge and the bartender hands him a shot of tequila. "First, you have to drink this shot without making a face."
The man quickly downs the shot and manages to keep a straight face. The bartender nods in approval and gives him the next task.
"Next, you have to go out back and pull the sore tooth of our angry pit bull without getting bitten."
The man hesitates for a moment but eventually agrees, determined to win the free beer. He goes outside and there is a lot of growling and yelping, but eventually, he emerges victorious without a scratch.
The bartender is impressed and presents the man with the final task. "For the last challenge, you have to make love to our 90-year-old waitress without laughing."
The man's eyes widen in shock, but he decides to give it a go for the free beer. He goes into the back room with the elderly waitress and starts to undress. As he looks at her wrinkled body, he can't help but burst into laughter.
The bartender walks in and says, "I'm sorry, you failed the challenge. But hey, at least you won't have to pay for drinks for a while!"
Defeated and humiliated, the man leaves the bar, wondering if the free beer was really worth it.
