I was so very impressed by Peele's film, Get Out. But in retrospect, I shouldn't have been. K&P already had a solid grasp of horror dynamics.
the Family Matters skit, gets downright freaky, Dubstep outperforms most crappy PG-13 horror ficks in 1/30th the time, and lots of the show's work will suddenly swerve towards the bizarre and unsettling on a moments notice (Continental Breakfast).
I can't pick just three, but the UFC Promo might be the one I've shown the most people, they just nail the details so damn right.
