Adam-12 - Season 4 - Eps 10: Day Watch
Over the course of their shift, Malloy and Reed deal with a racist gas station owner who is tired of being the victim of repeated robberies. When they catch the suspect, supposedly a black man, they find he is actually just an equally-racist white man in blackface. Other calls include a hitchhiker who extorts money from drivers she leaves in embarrassing situations, and a drunk who is seeing pink elephants.
