We're huge fans of Zac Efron here at Mr. Man, but even we have to admit that his younger brother Dylan Efron is giving him a run for his money maker. The thirty-two-year-old Zac Efron has majorly stripped down on screen in movies like Dirty Grandpa (where we even got a look at his balls and penis thanks to a rare package slip!) toExtremely Wicked, Shockingly Evil and Vile (where he flashed his meaty ass for a prison strip search) to Baywatch (where he didn't go nude, but did flaunt his wildly shredded bod in some of that year's hottest celebrity shirtless scenes).

So you're probably thinking "How could Dylan compete with all THAT?" And we'll tell you. While, no, sadly the twenty-eight-year-old Dylan hasn't joined his brother in stripping nude on screen, he has offered up someserious skin on Instagram. It wasn't that long ago that he posted a picture of himself peeing on the side of the road with his pants pulled down around his ankles. And this week he continued to chip away at Zac' legacy by shaking his supremely firm ass in his boxer briefs!

The... brief... video shows Dylan in some fire emoji undies. He wildly shakes his ass, but it's so tight that he isn't able to make his cheeks clap. In fact they barely move at all! Whether you prefer Zac or Dylan, when it comes to the Efrons, we all win...
