Oh man... if you're ever up for a prank for your office, you're more than welcome to call me and just start cussing and yelling and stuff.... Then I can show up at your work asking for you "the guy on the phone" and you can take me out back and beat teh ever living life out of me and then tell the office that they are next!!! HAAHHAHA
Well, I'd get fired for yelling at a customer, but there IS a portion of the office that customers can go to for certain services, so your idea has a lot of merit. We'd just both end up arrested is all. ;)
