Appearing on the Saturday Night Live 40th anniversary special Sunday night, comedian Martin Short mocked NBC for the ongoing scandal surrounding Nightly News anchor Brian Williams, declaring to the audience of A-list celebrities: “Do you realize that if this roof were to collapse right now, it would be the least of NBC’s problems?”

Minutes later, Jerry Seinfeld took on the Williams controversy directly, joking that the suspended news anchor had been an original SNL cast member.

During the red carpet show prior to the special, comedian Jim Carrey made the hosts of the Today show visibly uncomfortable when he asked: “Where are you hiding Brian Williams?”
