Lady Gaga performed a sketch on this weekend’s episode of Saturday Night Live where she summons a demon—and now, some people on the internet are stocking up on holy water and crosses, convinced the devil is among us.

With Lady Gaga serving as both the evening’s host and musical guest, Mother Monster had free rein to wreck creative havoc. For Lady Gaga’s first performance of the evening, she unleased true mayhem with latest album’s track “ Abracadabra .”

This Lady Gaga does everything: sings to mice, makes ritual sacrifices at Friendly’s, plans roaring-twenties funerals, and proves what a good actress she’s turned out to be.
