I worked with a guy who has carved out quite a niche being that dude in the commercial guy. Off the top of my head I know he is in about 5 Pizza Hut commercials as a delivery guy, The Hyundai commercial where he parks on a mound of dirt and puts a dog in the back of his UTE, wears a ballernia's tutu a commercial for the video game ATV Off Road and is in the McDonalds ministick golaie commercial as a guy on the bench.
I don't see his commercials listed on the imdb site.
