Ellen DeGeneres has a long history of scaring her talk show guests, and she did not disappoint when Jake Gyllenhaal stopped by on an episode that aired Wednesday.

In the clip, DeGeneres — seemingly innocent — asks Gyllenhaal about his preference for dark films. “I have this belief sometimes that if you go into the darkness it can be illuminating,” Gyllenhaal begins. But suddenly, the “Nightcrawler” actor is interrupted by a terrifying creature that pops out from a coffee table and scares him so badly that all he can say is “Oh my god, what the fuck?”

Watch the full clip above, and try not to scare yourself.
