The Situation from Jersey Shore needs to keep his shirt on, lest local police be forced to break up riots on the boardwalk. Talk about guns that need registration!

Seriously, though. The Sitch (real name Mike Sorrentino) was ordered to cover up last weekend after cops were concerned that his skin flashing could spark fights.

Police legitimately fear that The Situation shirtless may cause a large crowd to get violent. Not a bad bet, but imagine if this were Ronnie Magro after 8-10 drinks.

It all went down at the Aztec Ocean Resort in Seaside Heights, N.J., where the gang is back after a stint in Miami, and 3,000 people had gathered on the streets.

The occasion: Watching The Situation dance on a hotel balcony.

You can see how this right here could cause pandemonium.

According to the Seaside Heights Chief of Police, peeps were being and shoved in the crowd so hard that the Chief personally asked the Jersey Shore star to cover up and possibly tone it down before the crowd got completely out of control.

The Chief said later that The Situation totally understood and even put his shirt back on, but if you think this is the last you've seen of him shirtless, think again!

We hope this was caught on video. The Jersey Shore quotes would be priceless. We're also glad it wasn't Snooki dancing on a balcony. No one needs to see that.
