Malcolm in the Middle - Season 1 Episode 5

Because of Dewey always leaving food in the crawlspace under the house, the whole family is forced to live in a trailer owned by Lois' coworker, Craig, while their house is being fumigated. However, Malcolm ends up spending more time at the home of an upper-middle-class family who has hired him as their babysitter, but he learns that they were secretly videotaping him. He later blackmails the family to leave him alone and quits the job, also revealing a horrible secret about the family's wife. Meanwhile at the academy, Francis finds the corpse of a former janitor in the basement of the military school, who was missing for 16 years, and teams up with his friends to give the forgotten custodian a proper burial by sending him down the lake in a burned boat and performing a burial at sea, which turns into a disaster.
