“Saturday Night Live” kicked off its 35th season with Megan Fox as host — and the F-word.

From Tom Shales of The Washington Post:

Jenny Slate, one of two actors hired over the summer to join the repertory cast, was making her “SNL” debut in the sketch, called “Biker Chick Chat,” which aired in the last 20 minutes of the season premiere. Slate and Kristen Wiig played surly motorcycle babes who used the substitute words “frickin’ ” or “friggin’ ” in every sentence they spoke.

But when, at about 12:43 a.m., Slate was supposed to say to Wiig, “You stood up for yourself, and I friggin love you for that,” she mistakenly said the real f-word instead. Slate made a face — puffing up her cheeks, basically — but the sketch went on with no other problems.

Lorne Michaels, the show’s executive producer, said from New York late [Sunday] that the moment was especially traumatic for Slate because “it was literally her first time on the show. There was nothing dirty, just a slip of the tongue. It was ‘frickin’, frickin’, frickin’ ‘ and then boom! The pain that Jenny is going through is, I’m sure, considerably worse than that experienced by anybody who saw it.”

The virgin ears of “SNL” viewers on the West Coast weren’t subjected to the obscenity. The intended “frickin’” was dubbed in its place.
