Zac Efron [1] without a shirt truly is one of life's simple pleasures, which is why we have a whole article dedicated to the phenomenon [2]. He's shedding his clothes once again for the road-trip comedy Dirty Grandpa [3], and we couldn't be happier about it.

You can bet we'll be updating this should more shirtless [5] pictures become available, so stay tuned.

Also, here's this cropped picture, in case you want to save it for later.
