He's best known to a certain generation of fans as Principal Duvall from Mean Girls, but he's a bona fide comedy legend! Meadows is one of the longest-running cast members in Saturday Night Live history and most recently has played John Glascott on The Goldbergs and its spinoff Schooled. This won't be his first collaboration with Sandler, either: they've worked together on several movies, including Grown-Ups and its sequel, as well as the notorious flop Jack and Jill.
