Schwimmer hosted SNL back in 1995 as part of Season 21, and he was quite busy at the time, because he was also filming one of the best sitcoms, Friends. While appearing on The Late Show with Stephen Colbert, the Ross actor shared the schedule he had the week he hosted, and it didn’t give him much time to rehearse for SNL, as he explained:

David Schwimmer made a “big mistake” when he hosted Saturday Night Live in 1995, he revealed on Late Night With Stephen Colbert. “It wasn’t until years later” that he found out what he’d done to rub SNL writers the wrong way,

The actor said he was "the first in the cast of 'Friends'" to be invited to host the long-running sketch comedy show
