Museums across the globe are battling it out on social media - over which exhibit features the best butt.
The Butt Battle started when the Yorkshire Museum tweeted out a photo of a Roman statue's derriere, declaring it "depicts an athlete at the peak of fitness!"
London's Wallace Museum responded with a statue of a nude Hercules showing off some muscular glutes. Another entry featured a statue of 'Aphrodite Kallipygos', which translates as "Aphrodite of the beautiful buttocks".
Dozens of museums have shown off their best behinds using the hashtag #BestMuseumBum - including butts belonging to Napolean, Zeus, and even ancient Japanese sumo wrestlers.
