It's not rare to see Zac Efron shirtless these days -- here's a handy guide to his shirtless roles -- but it doesn't make us any less thankful when it happens.
His abs' most recent appearance came in a clip from the premiere of Bear Grylls' new reality show on NBC, Running Wild, where the pair skydive into the Catskill Mountains of New York and, at the suggestion of Grylls, take their shirts off to rappel down a cliff. No complaints here.
The series will see other A-listers, including Ben Stiller and Channing Tatum, left in similar remote areas experience "high-octane, action-based and empowering journeys" with Grylls -- and his camera crew.
