A even better prank is the "strip search prank" ( http://abcnews.go.com/Primetime/story?id=1297922&page=1 )where you call a business that is staffed by morons, say Mcdonalds or taco bell. You tell the manager you are a police officer, and describe a female employee you know is working, and tell the manager she was reported to of just stolen a purse and the manager needs to get her in the office before she escapes. You then tell the manager to strip search the girl, and then do jumping jacks to make sure "nothing falls out". You tell the person that the girl has to call them sir or maam, when they don't, you make them spank the girl for 10 minutes until her bottom has welts.
This one caller has SUCCESSFULLY done this dozens of times:
early 2004, there had been more than 70 cases of hoax phone calls to fast food restaurants, dating as far back as 1994.
At a McDonald's in Hinesville, Ga., a caller convinced a 55-year-old janitor to do a cavity search of a 19-year-old cashier, while in Fargo, N.D., a manager at a local Burger King strip-searched a 17-year-old female employee.
In Phoenix , a caller had a Taco Bell manager pick out a customer and then strip-search her. And police in Massachusetts had been looking for a man who called three Wendy's restaurants nearBoston in a single day.
