Zac Efron is one of our very favorite Mr. Man celebrities, but it seems like his nude days might be behind him for now. None of his six projects in development on IMDB appear to be particularly sex-focused (although on the reality series Killing Zac Efron he will return to the jungle ala Running Wild With Bear Grylls, so who knows). But that doesn't mean we can't relive the whorey days by checking out Zac Efron's best nude scene to date! Where, yes, we can see that his scrotum is lower than his penis.

Depending on who you talk to, Zac Efron's hottest scene to date can be found in the 2016 comedy Dirty Grandpa. This was before Zac Lou Ferrigno-ed out for his role in Baywatch, so he was slightly more naturally athletic and svelt looking. Not that you can go wrong with Zac Efron! I just prefer my hairy 2016 jock with the face of an angel and the ass of a male gymnast.

Thirty-five minutes into Dirty Grandpa Zac finds himself asleep on the beach wearing a stuffed animal hornet as underwear. A beachgoer tries to pry away the hornet, and as Zac scrambles to cover himself, we get a clear look at his penis and balls - our only frontal shot of him to date! You can see pubes, and you can see that despite the girthy look of his cock, his balls actually hang a little lower. If you know us...

... you know we don't harbot any hatred for big low-hanging balls. Psst, we love 'em! So relive the hottest that Zac Efron has to offer with his frontal scene from Dirty Grandpa. We'll just call him Sac Efron!
