When you're an up and coming comedic actor with a couple box office hits under your belt, you can pretty much cut the old suit and tie routine. So, we're not really sure why Seth went with this look at the premiere of his latest buddy comedy Pineapple Express.

If you're not into dressing up, that's cool. Go with a t-shirt and blazer or something, rather than just half-ass it. The suit fits OK, but he's obviously not trying to pull it off. Rogen seems like a pretty casual dude, why not go with what's natural? Maybe Judd Apatow put him up to it.

Also, when you're starring in a movie named after a super-potent strain of weed, and you show up to the premier all unbuttoned and smiley -- it looks kinda bad. Standing in front of a bunch of pot leafs doesn't really help either.
