Men at Work (1990)

Carl Taylor (Charlie Sheen) and James St. James (Emilio Estevez) are garbage men who spend their workdays goofing around and disrupting the quiet on the streets of their town. But their good-natured fun comes to an abrupt halt when they discover a local politician's corpse in one of their cans. Determined that this is their chance to be more than trash collectors, this snarky pair of amateur detectives decide to solve the case on their own and so become entangled in a toxic waste cover-up.
