There may just be an R-rated Superbad-meets-Willy-Wonka movie in here somewhere. Playboy top dog Hugh Hefner has announced a contest that will give out 10 "golden tickets" to readers of the venerable magazine. Those who root out those pieces of paper, stuffed into newsstand copies around the country, will win a VIP trip to the infamous Playboy Mansion for a Midsummer Night's Dream party next August (which is more like late summer, but let's not nitpick). Should we expect fans to go on massive buying and hoarding sprees, like they did for those Wonka chocolate bars? Hef, who's riding herd over a financially ailing empire, can dream. Playboy.com, which is tracking the sweepstakes, says no one found any tickets over the weekend, but the pub just went on sale Friday. There's still plenty of time for people to paw through their copies and start planning their grotto-centric vacations. Hef has never opened up the Los Angeles manse to readers before, though the stunt will only admit a handful of (potential) riffraff. They'll hardly stand out at all.
