Movies That Inspired TV Sitcom Plots

Doesn't that episode reminds you of some movie?

No, I'm not talking of an umpteenth parody of Reto al destino (1982) or another use of Psicosis (1960) screeching violins, but an entire plot that is inspired by a classic movie. If you can count at least 3 sitcom episodes based on a film (even in a loose way), they're in for the poll...

Overall, which of these movie plots that inspired sitcom episodes worked the best?
