The Munsters: Mummy Munster (1965) (TV)

Synopsis [spoilers]: Herman volunteers to take Marilyn to the museum for some school research of hers; he doesn't stay there, though: Lily is afraid that he will get into trouble, as is his habit, and tells him to return home and later go back to pick her up. At home, Grandpa gives him a sleeping pill that he just invented: it is so sophisticated that one can adjust the hour it will kick in, and the duration of its effect. Herman returns to the museum but gets lost in there and Marilyn, after waiting a while, goes home by herself. The museum closes and Herman, still inside, decides to call home. He sees a newly acquired sarcophagus and mistakes it for a phone booth. He enters it and the lid closes; while he is trying to get out, he begins to feel the effects of the sleeping pill he took, and falls asleep. In the next morning, they open the sarcophagus for the first time and, seeing Herman inside, think he is the mummified body of pharaoh Amenhotep. The Munsters are worried about Herman's whereabouts when Eddie shows them Herman's photo in the newspaper's front page. Lily comes to the museum and claims her husband; they think she is insane. At that moment she can't prove that Herman is alive because he is under the effect of the pill until that night (well, whatever...). They keep a watchman on Herman to prevent him from being stolen, but he gets so scared by the sight of Herman returning to consciousness that he breaks out of the museum through its door, freeing the passage for Herman. At home, Grandpa convinces Herman to take another pill and he falls asleep again. The museum curator and his assistants come to the Munsters' house to search for Herman and, finding him asleep, take him back to the museum. During the trip back to the museum Herman awakes and everyone in the car gets frightened and gets out of it while in motion.
