A man walks into a bar and orders a beer...

A man walks into a bar and orders a beer. He looks around and notices that there are big chunks of meat hanging from the ceiling. Puzzled, he asks the bartender, "Why have you got all this meat hanging around?" The barman says, "It's a little bet we have running. If you can jump up and grab a bit of meat in your mouth, then you can drink for free. If you fail, then you have to buy everyone else in the bar a round. Are you going to try?" The man shakes his head and replies, "No, the steaks are too high."

This is a pun. The humor lies in the last sentence of the joke. The guy saying that the steaks are too high could be saying that the pieces of meat are too high to reach when jumping, but he could also be saying that "the stakes are too high", which is to say that the risk of the bet is too great (buying a round for everyone is too much money).
