Since he (and James Franco) are pimping the hell out of their new film Pineapple Express at the moment, Seth Rogen went down to the Late Show studios in New York for a bit of a chat with David Letterman last night.

The sound/visuals are a little out but it’s a fun interview - which ends with him leaping into a pool of, presumably, dog saliva. It starts a little abruptly though - they’re talking about the doggy dock diving competition.
