You probably have a Halloween hangover by now, but we had to share the results of Adult Swim's awesome Your Pretty Face Is Going to Hell  Snapchat tie-in.

Satan's corporate minions marked the ghoulish occasion with a one day-only Snapchat filter allowing fans to demonize themselves, and the show's cast and fans—from Conan to Kylie Jenner—wasted no time jumping on the bandwagon.

Satan himself (okay, actor Matt Servitto) got in on the fun, and even brought his demonic daughter.

You can get the full rundown over on Storify, and be sure to catch Your Pretty Face Is Going to Hell Sundays at 11:30 p.m. ET on Adult Swim.
