Stop everything and take a moment and enjoy this photo of Zac Efron ... because, don't we all need a little more Zac Efron in our lives?
The actor is looking better than ever these days -- and Wednesday, on the set of his upcoming movie "Townies," he put his bulging biceps on display in a tight, white fraternity t-shirt.

Think you can identify other male celebs by just their buff biceps? Try it out in the gallery above -- and enjoy!
