Watch '30 Rock,' from EW's New Classics Collection
Few comedies anymore know how to build a gag over an entire episode, much less an entire season. The “MILF Island” episode of 30 Rock, which you can watch in full below, takes a throwaway gag from last fall’s season 2 premiere and develops it into an entire episode. (Viva DeBorah!) The delightfully absurd result is one reason why 30 Rock landed at No. 47 on our list of the Top 100 TV Series of the last 25 years in the current EW 1000 issue.
