Rude Awakening
This bed fart footage is from the movie called LOVE STINKS (1999).
Seth (French Stewart) is a TV writer dating Chelsea (Bridgette Wilson), who wants to get married ASAP. In the process of trying to advance their relationship, Chelsea pushes Seth farther away and they both start going over-the-edge wacko towards each other. This movie leads to some very dark, sophisticated and low-brow humour all at the same time. - Thanks to Erin for this info.
