OK, so it's been a couple of days since Zac Efron completely stole the show during his guest appearance on Running Wild With Bear Grylls, but no matter how much time passes we just can NOT shake the episodes from our heads!
Maybe it has something to do with the REAL star of the show: Zac's amazing abs!!
Watching Zac and Bear survive in the wilderness while forming a bromantical bond for our viewing pleasure would have been enough on its own, but the fact that the hunky actor was shirtless for the most part just makes it that much better!
So we thought we'd do the world a favor and take a look back at some of the best shirtless moments from the episode!
