Zac Efron Has To Strip If He Wants To Survive In New Running Wild Clip! Watch Him & Bear Grylls Get Shirtless And Rappel Off A Cliff Together HERE!

Rule number one if you’re Zac Efron and you want to survive out in the wild: take your clothes off!
As much as it seems like we’re kidding around, that was the ACTUAL advice that survival expert Bear Grylls gave Zeffie while the two were out in the middle of nowhere on his new show Running Wild!
Bear baited Zac into taking off his shirt and repelling off of a cliff with him!
So much muscle! So many abs!
And so it is with much appreciation that we say, thank you, Bear Grylls!
This wasn’t the only death-defying feat Mr. Efron had to endure though!
