In chopping spree there is an aerial view of a car wash that face uses to wash his car after a failed chase. That car wash was the same one used in the 1976 movie Car Wash the footage used is from the movie itself though it was an alternate clip. if you check out the cars parked at the shell station beside the Hot Dog House you will see they are the same in the TV show and in the movie but the street traffic is different between the two.
In the scene where Friendly attempts to throw Face off of his car lot, Friendly calls to a very large man washing the cars named Jack. Jack was played by actor/stuntman Ben Bates. Bates was also in the film Ruckus, which also starred Dirk Benedict. In the film, Bates plays a local redneck that also has a penchant for harassing Benedict.
