Looks like Shia has shown off the full LaBeouf in this new "Nymphomaniac" trailer. Needless to say, the first real look at the, er, action in Lars Von Trier's epic, five-hour movie showing one one's erotic journey from Milan to Minsk childhood to adulthood is completely, utterly not safe for work.

Previously, we've gotten little teasing tastes of the movie, ranging from what are essentially the "did someone order a pepperoni pizza?" scenes, to some posters that showed the stars mid-orgasm. But for fans of celeb nudity, this is the best Friday of your lives.

The montage of scenes in the (did we mention not safe for work?) trailer titled "Chapter 5: The Little Organ School" show off piano playing, toy cars, and nearly every sex act you can imagine, featuring a very, very naked Shia LaBeouf, and a very naked Stacy Martin. Either that, or this is the raunchiest outtake from "Even Stevens" ever.

"Nymphomaniac" hits theaters on December 25, 2013, which officially makes this the most uncomfortable Christmas of all time. No word on whether LaBeouf had any concerns about being put in a chapter titled "Little Organ School," but we guess you can judge for yourselves.
