In the off-Broadway spook show Play Dead, master magician Todd Robbins delights in pointing out that illusions are merely that. Mind-reading: fake. Speaking to the dead: fake. Audience members disappearing in plume of sulfuric acid: fake. But he performs one trick that’s shockingly, horrifyingly real.

So real, that Kurt had to see it up close. The video below speaks for itself, but it always bears repeating: don’t try this at home.

This weekend on the show, Kurt talks with Teller, “Play Dead”‘s co-creator and director — he reveals a couple of the creepy things they do to audiences in the dark. (Related shocker: Teller, the silent half of the magic/comedy duo Penn & Teller, speaks.)
