These unaired "Saturday Night Live" dress rehearsal sketches keep getting better and better. Last week's unaired sketch featuring Bill Hader and Fred Armisen as New York City doormen was good enough for the show. This week Martin Short goes back to high school to geek it out in a 30-year reunion of a teen sitcom. It's not quite as great, but still worth a watch.
