We almost forgot that these two were jumping off a cliff.
Before Zac Efron and Bear Grylls scaled down a massive terrain in New York's Catskill Mountains on Running Wild With Bear Grylls, they kicked off the show's clip in the best way ever: by stripping off their shirts (how else would Efron do it?!).
The Neighbors star and thrill-seeking host showed off their chiseled abs and toned arms as they stood at the top of a high cliff, put their shirts in their backpacks and tossed them into the water below so they'd have dry shirts when they made it down.
Surprisingly, going shirtless was not Efron's idea. It was Grylls', and for that we are thankful.
This was just the first of the daredevil stunts the 26-year-old thesp participated in while hanging out with Grylls. He also convinced Efron to go skydiving…and caught the moment he jumped out of the plane on cam.
"We reached out to him and he kindly said he was a fan of the show and that he was in 120 percent," Grylls told People. "He asked for the biggest, baddest adventure and it was an honor to oblige."
The Running Wild With Bear Grylls episode featuring Efron airs July 28 on NBC.
