Practical joke literally comes back to bite man in the ass

Smarter and sillier-dressed people than I, like ancient Greeks and college drama professors, have come up with complex theories about what constitutes tragedy and comedy. I think I can break the two down into slightly more simple formulations. Tragedy is when bad things happen to good people, whereas comedy is when bad things happen to stupid people:

Utrecht police say a 21-year-old Dutch man is recovering after a "mooning" that went horribly wrong.

A police statement says the man and two others had run down a street in Utrecht with their pants pulled down in the back "for a joke."

It says that at one point the 21-year-old "pushed his behind against the window of a restaurant" that broke and resulted in "deep wounds to his derriere."

The statement released Tuesday says police detained the three men after the incident Sunday morning. But the cafe owner decided not to press charges after the men agreed to pay for the broken window.

That's really too bad. Because this was clearly a case where insult was just begging to be added to injury.
