To quote Jim Carrey in Ace Ventura: Pet Detective, we'd like to "ass you a few questions." First off, what exactly are the greatest butts of all time? Prodigious posteriors have been jiggling their way to pop culture prominence for years now, thanks to bottom-heavy Internet breakers like Kim Kardashian, Nicki Minaj, and legions of amazingly-endowed Instagram lovelies (we're talking to you, Jen Selter.) It's the Golden Age of Ass, and that's something we can definitely get behind (see what we did there?). But it's not like amazingly round rumps didn't exist before the advent of the "belfie"; men have been admiring asses since we lived in caves. So without further ado, Maxim presents some of the most bodacious butts ever. To the rear, march!
