I might be the only man on Earth who had never heard the phrase “jam out with your clam out,” but at least I’ll go into Harold and Kumar Escape from Guantanamo Bay having heard all of its jokes before. The new R-rated (NSFW) trailer for the sequel to Harold and Kumar Go to White Castle (via Movie City Indie) is plenty hilarious. I just have the feeling that it gives too much away.

Here are some gags that could have been saved for the actual movie: George Bush smoking pot and saying the words “cock sandwich”; the one-eyed inbred son in the basement, which comes after an obvious set-up, anyway, and which reminds too much of the tow truck driver’s house in the woods from the first movie; and the Ku Klux Klan sequence, which feels ripped straight from O Brother, Where Art Thou? – it will likely still be funny in the movie, despite its being familiar, but there’s no need to make us feel like the movie won’t be fresher than a sack of chicken rings.

That said, there are also plenty of great bits in the trailer that both are satisfying and leave me craving more. For all its derivative sequences and jokes and its seemingly dated concept (9/11- and Guantanamo-based movies are so 2006), Harold and Kumar Escape from Guantanamo Bay still looks like the most awesome gross-out, stoner comedy ever. And it captures and references enough of the first movie to please those of us who (suprisingly) fell in love with these two potheads. Yet it also promises more than simply a wild road trip full of laughs — now there’s an antagonist! … and political satire!

I think I’m looking forward to this one more than The Pineapple Express, and coming from a big fan of both David Gordon Green and Seth Rogen, that’s some serious anticipation.
