When Saturday Night Live returns for its 39th season, three longtime actors (Fred Armisen, Bill Hader & Jason Sudeikis) will no longer be part of the cast. Insert sad face. As they say, the show must go on. Just as the case when the unexpected happens during a live show.

Typically, the show’s strong arsenal of repertory players have no problem keeping in character no matter what comes their way. But every now and then, they fall prey to laughing fits. Just like the common cold, it then becomes extremely contagious and pretty soon everyone’s trying not to bust out laughing.

In a new supercut, everyone from Phil Hartman to Jimmy Fallon, Will Ferrell to Bill Hader’s fit of laughter is documented. Check out the hilarious clip below.
