All of these performers were widely responsible for the sketch comedy show’s resurgence in the 90s, along withConan O’Brienhimself, who was a staff writer on the show before landingLate Night with Conan O’Brienin 1993. During last night’s episode ofConan,Norm MacDonaldblew the lid off what might possibly be one ofSNL’s biggest secrets.

Norm MacDonaldjoined the show in 1993, right whenConan O’Briengot theLate Nightgig.Adam Sandlerspoke about how excited everyone was forConan, and that they all got together and watched the show withChris Farley, whomNorm MacDonaldhad never met at this time. We have a clip from last night’s episode, courtesy of theTeam CocoYouTube, whereNorm MacDonaldreveals howChris Farleyshared one ofSNL’s biggest secrets with him, on the first night they met.

“He took me back, he said, ‘I’ve got to tell you a secret aboutSNL.’ He secreted me into this room and he locked it and made sure it wasn’t bugged. He said, ‘I got a secret to tell you.’ I was very honored to have this. And then his secret was - he said, ‘This doesn’t go past these walls. Pat is a woman!'”

The “It’s Pat” sketch, performed byJulia Sweeney, was among the mostpopular sketchesat the time. The sketches always revolved around the sexual orientation of the androgynous Pat, with supporting characters trying to decide whether Pat is a man or a woman. The character even made the transition to the big screen with the 1994 movieIt’s Pat, but it was an utter box office failure, earning just over $60,000 during its brief theatrical run.
