Seriously? When have they done something that, if real, would be devastating to the victim (I'm honestly asking because I've only seen the show a few times)? The ones I've seen have to do with children asking sports stars to autograph 100s of items, roadblocks keeping people from getting to their photoshoot or appearance on leno, people being fired from restaurants (and blame being placed on the celebrity), etc. I think if it's tasteful, it can be hilarious for them to punk Kelly.
