Started watching freaks and geeks on Hulu and its pretty good. High school show from 2000 with tons of people who are now famous for other things (james franco/seth rogen/jason segel etc).
Also alot of random guest stars like whoever plays Ann in parks & rec, Jason Schwartzman, David Koechner, Shia Labouf etc. Its fun watching it and being like "wait a second, I know that person".
