A man walks into a bar and notices a jar full of money behind the counter. So he asks the bartender, "What's that jar for?"
The bartender replies, "Oh, that's for our ongoing joke challenge. If you can tell me a joke that no one in the bar has heard before, you get to take the money in the jar."
The man thinks for a moment and then confidently says, "Okay, here goes. Why couldn't the bicycle find its way home?"
The bartender and everyone in the bar look at each other puzzled, and after a moment of silence, the bartender shrugs and says, "I don't know, why?"
The man grins and proudly says, "Because it lost its bearings!"
The bartender and everyone in the bar erupt in laughter, and the man happily takes the money from the jar. As he's leaving, the bartender asks, "Hey, can I use that joke in the challenge too?"
The man winks and says, "Sure, but it'll cost you a drink."
