Ryan Gosling is a seasoned, Oscar-nominated actor. But hosting "Saturday Night Live" is unlike any other showbiz gig — and when Gosling hosted for the first time this weekend, his giggles got the better of him.

Gosling started stifling grins during the monologue, when fellow Canadian Mike Meyers appeared to sing a Great White North-themed Christmas number.

But later, during a sketch where he, Cecily Strong and Kate McKinnon portrayed pals who had been abducted by aliens ... well, that was the end of the straight face for the 35-year-old stud.

He wasn't alone: "SNL" cast members Bobby Moynihan and Aidy Bryant were also having a hard time holding it together during the sketch, which of course made everything that much more hilarious for everyone — especially the audience.

Other highlights of "The Big Short" star's appearance included a sketch where he and Vanessa Bayer played an adult couple who still believe in Santa and a turn as his movie star self, bumping into a high school bully at a hometown bar in Ontario.
