Deathtrap

"Deathtrap" is the nineteenth episode in season 9 of American sitcom Frasier. The first scene of this episode is a flashback to Frasier and Niles as schoolchildren, stealing a skull from the school science laboratory to use in a production of Hamlet. The Cranes' old family house is up for sale, and Frasier and Niles decide to pay it another visit, wondering if it would be worth purchasing and turning into a bed and breakfast. The owner, Mr Lasskopf, has no memory of them, but Martin remembers that he never returned their security deposit. The brothers soon realise that the house is too small to be a bed and breakfast, but then they remember that there is a memory chest hidden under a loose floorboard, so they return secretly after dark...
