Ashton Kutcher, the actor and reality impresario who presides over Punk'd as intently as if he were Martin Scorsese with a whoopee cushion, is one of the producers of this show inspired by Vince Vaughn's movie Wedding Crashers. Here the bride and groom are in on the gag: Their ceremony and reception will be subverted by actors pretending to be planners, ministers, caterers and so on. It's only family and friends who end up fooled. Apart from the fact that the gags aren't funny—a waiter takes away guests' plates still loaded with food—it's off-putting to see something sacred being mucked around with. What's next? Crashing funerals?
