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.
