Weekend at Bernie's
It was a bit slow at times, but the fashion and 80s slang made up for it. Where can I get my hands on a pair of light-purple high-top Converse!?! The concept of pretending your obviously dead boss is alive to allow for a party to continue is so stupidly funny; weirdly enough, the concept of this film is more popular than the actual film itself.
SNL did a good digital short inspired by it, which I have to mention because it pretty much sums up what would have happened if the people noticed he was dead: https://youtu.be/G-vUVc-lEgo?si=Mh-QJXKfVYd2xHIi
