I love a good prank, especially a good prank around the office. The best prank I'd ever seen at an office happened a few years ago when someone unplugged our copier and then put a sign on it, complete with the copier's logo to make it look "official" and real, and the sign said something to the effect of "our copy machine is now voice activated. In order to begin, please say your name." Of course, since it was unplugged (and also not actually voice activated!), nothing happened and we had sales people standing around it all day yelling their name trying to get it to work as it just sat there. As you can imagine, a few lost their patience. It was all pretty funny.
Jimmy Kimmel played a pretty good prank on his office people too, and they caught it on camera for his show. A wax figure of Jimmy will be on display at Madame Tussauds in Hollywood, and before putting the figure in the display, they brought it to his office to have some good fun... and this is SO MUCH fun!!! And pretty darn hilarious.
Poor cousin Micki...
