Amman, Jordan apparently has some serious pranksters, because there was a UFO prank that sent many people into panic, keeping kids home from school and almost caused a towns emergency evacuation! The prank took place in a Jordanian newspaper over April Fools Day. The newspapers story reported on a UFO visit that lit up a small desert town, messed up communications and sent people fleeing into the street, then added the visit from the 10 foot tall aliens. The panic was a very similar result to the 1938 radio show 'War of the Worlds'.
