Derren Brown, possibly the most unsettling mentalist currently on the magic circuit, paid a visit to The Late Late Show with James Corden last week. The usually affable Corden may have regretted the choice of guest when Brown asked him to put a shard of a broken light bulb on his tongue and then eat it. Corden managed to eat the glass fragment with understandable amounts of trepidation and coaching from Brown.

“What’s going on?!?!” Corden yells at one point. Took the words right out of my mouth, James.

If you want more of this decidedly unnerving approach to mind games, then check out Brown’s special The Push, which recently became available on Netflix. And then you’ll need some patience, because he’s got another Netflix project still in the works.
