Of course it's not a threesome in the sexual sense. There's some kind of explanation in the picture about what you really win in the contest--the fine print is on the microscopic side, but I'm pretty sure it says something about how you win lunch or a movie outing with the actress. (Details are on Johansson's site, but it's down right now, probably overloaded with eager submissions.) Doesn't it sound like it should be the plot of a Three's Company episode where Jack wins a date with some hot celebrity babe, but then has to bow out at the last minute lest Mr. Furley's hetero suspicion fall upon him? Or maybe it sounds like that Robot Chicken where exactly this happened.

There will probably also be many more than three people involved. There's Johansson, the contest winners, a gaggle of paparazzi, at least one legit media person, Johansson's assistant, someone "official" from the movie, and a professional perv wrangler or two. When you add them all up, it starts sounding more like an orgy than a threesome.
