Jim Carrey Jim Carrey

Jim Carrey returned to Studio 8H to host Saturday Night Live's Halloween episode this weekend, and offered fans a sneak peek of his inventive Halloween costume, as well as the upcoming Dumb and Dumber To (sort of).

Proving that Carrey can still do physical comedy just as well as subtle humor, two of the episode's funnier bits were recurring commercials that mocked Matthew McConaughey's current campaign for Lincoln, and a dance-off between Carrey and Kate McKinnon to Sia's "Chandelier."

Check out some of the highlights below:

Jim Carrey's Monologue: Carrey unveils his Halloween costume, Helvis, and kicks the night off with a musical ode to pecan pie.

Lincoln Commercials: Carrey's impression/mockery of McConaughey's serious self-reflection in the Lincoln ads is flawless.

Carrey Family Reunion: Take a trip down Jim Carrey Memory Lane with this family reunion sketch, in which the cast does their best impressions of Carrey's most memorable characters. Also: Jeff Daniels drops by to give us a taste of Dumb and Dumber To.

Ghost Chasers: In her first episode as a featured player, Leslie Jones shines in this sketch where she plays a "resident skeptic" among a group of ghost hunters.

Halloween Party: After two guests at a Halloween party (Carrey and McKinnon) both come dressed as the child from Sia's "Chandelier" video, obviously the only way to determine who wore it better is through a dance-off. Look for a cameo by musical guest Iggy Azalea.
