A 21-year-old Dutch man has been hospitalized with severe lacerations to his backside after an attempted mooning went terribly wrong.

Three men were reportedly walking down the street in Utrecht when they decided it would be fun to pull down their pants "as a joke" and run down the street flashing passersby. But when one of the crew leaned his derriere against the window of a restaurant to show his wares to patrons dining inside, the pressure from his posterior broke the window and the shards of glass sliced into his rear end, leaving him with what police are calling "deep wounds."

The three men were arrested for the incident, but the restaurant owner dropped the charges after they agreed to pay for the broken window.

Bare butts we'd rather see ...

Another stupid way to hurt yourself ...
