SNL: Watch Jim Carrey Dance to Sia and Impersonate Matthew McConaughey

After one of its least-watched episodes ever, alumnus Bill Hader’s hosting gig on Oct. 11, Saturday Night Live brought out the big guns again this weekend, with veteran host Jim Carrey and earworm-of-the-summer victor Iggy Azalea, who took a “Fancy” victory lap by performing her brand-new single “Beg for It.”

Below are three highlights from Carrey’s hosting gig:

“Halloween Party”: After Carry and Kate McKinnon’s characters both show up to an office Halloween party dressed as Maddie Ziegler from Sia’s mesmerizing “Chandelier” video, they decide to settle their costume contest rivalry with — what else? — a dance-off. The two then proceed to run, slide and gyrate all over the set in an epic reenactment of the video’s eccentric choreography, even letting Iggy Azalea in on the fun at one point.

“Lincoln Ads”: Time has never been a flatter circle than in this fake car commercial, which utilizes Carrey’s well-known skill as a mimic for an eerily accurate Matthew McConaughey impression that’s half pep-talk persona, half True Detective philosophical monologue. Choice quote: “Sometimes you gotta go back to actually move forward. And I don’t mean go back and reminisce or chase ghosts. I mean, take a big step back. Like go from winning an Oscar to doing a car commercial.”

“Carrey Family Reunion”: All the trademarks of Carrey’s comedic acting get roasted in this sketch, which finds the actor reuniting with some of his most iconic roles–the Riddler, the Mask, the Cable Guy, Ace Ventura–as well as with Dumb and Dumber co-star Jeff Daniels. (The two are back together again in Dumb and Dumber To, which hits theaters next month.)
