I love really bad cheesey commercials. The cheesier the better. There's a local one here for Action Jack's furniture with a guy in drag in this really crazy outfit. His/Her name is "Big Beulah," and s/he is doing that karate move where you chop a board in half. At the end, s/he tries to chop a cinderblock brick and hurts his/her hand. I don't know what that has to do with furniture, but I love it.
Action Jack's Furniture store, by the way, is run out of a storage unit.
I also love the commercials for Sonic with those two guys in the car. I especially like the one where the one guy is counting carbs. And the one where the other one has stopped eating vitamin E.
And I know I've mentioned this before, but my favorite infomercial is a local one for Earnhardt's used cars. It's called "Credit Court" and it's supposed to be one of those court TV shows. My favorite character is Trixie, Dead-Beat Dad's girlfriend he met at the trailer park.
