Ewwww!

It's the celebrity version of Running Wild With Bear Grylls on NBC!

Zac Efron really tires a worm, which you can see a preview for the show that premieres July 20th. 

The show is unscripted and looks pretty funny! You can see Efron, Channing Tatum, Ben Stiller, Tamron Hall, Deion Sanders, and Tom Arnold also on the show.

Will you tune in to watch it?
