'A Very Harold and Kumar 3D Christmas' Trailer: Everyone's Back for More Hijinks (Video)

Harold and Kumar are back!

The official trailer for A Very Harold and Kumar 3D Christmas has hit the Internet -- and the pair is back to their old hijinks. it starts off like any other holiday flick, that is, until Harold (John Cho) shoots Santa Clause. "I shot Santa Clause in the face," he says. "He's real and I shot him in the face." Well, things get crazier and crazier from there.

At one point, Harold and Kumar (Kal Penn) see clay versions of themselves. "Dude, we're Clay-mated," Harold says. "Awesome!," Kumar replies.

Better yet, the film is in 3D, but the filmmakers were smart enough to poke fun at the recent 3D explosion. "I don't know, hasn't the whole 3D thing jumped the shark by now?"

Neil Patrick Harris also returns as himself. A Very Harold and Kumar 3D Christmas opens in theaters Nov. 4.
