For how iconic this teen show has become and how stacked that cast was, it's wild to remember how the series was treated back in 2000. Three of the 18 episodes didn't even air on NBC with the rest of the series, and were only seen when the show aired on Fox Family a year after it had premiered, and the actual final three episodes aired four months after the previous episodes. Rude, honestly.
But at least in the years since, Seth Rogen, Busy Phillips, Linda Cardellini, James Franco, John Francis Daley, Jason Segel, Martin Starr, Judd Apatow, and Paul Feig have all gotten their revenge.
