Jim Carrey's Back in These 'Saturday Night Live' Promos

Jim Carrey's back hosting 'Saturday Night Live' this weekend, as we're reminded in these promos the comedian shot with 'SNL' cast member Jason Sudekis. There's also a long look at Jim Carrey's back -- as in the other side of his suit-clad torso -- in the minute-long clip.

Bonus: Old school, crazy face-making Carrey makes an appearance. "I'll be using a mixture of sound, movement and funny faces to beguile the audience," he tells Sudekis. Sweet.

The Black Keys are the musical guest. Watch the promo for tomorrow night's show after the jump.
