JK Simmons SNL Promo H 2015

J.K. Simmons is hosting Saturday Night Live this weekend, and in the promos for the gig, he's already dragging. Or rushing.

Either way, he's "not quite my tempo," says SNL cast member Kenan Thompson, in reference to the tense rehearsal scene in Whiplash with Miles Teller — complete with a slap or two.

Also in the promos, Simmons and Thompson poke fun at the not-so-intimidating blizzard that brushed over New York City this week, as well as what Simmons' initials actually stand for. Thompson's best guesses: "Jungle khaki? Jellybean kink?"

It's the first time the Whiplash star is hosting the NBC sketch-comedy show. The musical guest on the Jan. 31 episode will be D'Angelo, who recently surprised fans with his first album in nearly 15 years.
