A prank sworn to my my old friend Alberto Vazquez (I'm reminded of it by an earlier prank in this thread):

A friend of Alberto's was an astronomer in Arizona (U. Of?) and his observatory was far away from the city lights. The parking lot for same became a lovers' lane, so one day he arrived at work to find the parking lot closed off by a chain. And him not given a key, of course. So he got out his handy bolt cutters and snipped the light chain, drove in and parked, and went to work.

Next day, a heavier chain; Bolt cutters still worked, though. Next day, heavy duty chain and big-mother lock. So he jacked the posts out of the ground.

Then he waited till the University workmen arrived to set the posts in, this time with concrete. Once they were well on the way to accomplishing this, he called the campus police and said, "A bunch of fraternity boys, dressed as campus workmen, are closing off access to a campus parking lot."

A few, carefully-timed minutes later, he called the city police, and said, "A bunch of fraternity boys, dressed as campus policemen, are harrassing University workers here at the observatory."

Then he sat back to watch the fun. Eventually, the University gave up on blocking off the parking lot (or gave him a key, or something like that).

This story is true, even if it never actually happened.
