Museums are stepping up on social media with fierce curator's battles over whose collection holds the #BestCat, #MysteryObject and #BestMuseumBum—for figures in art boasting backside⁠—human or animal, apparently.

Yorkshire Museum in the U.K. kicked off the near-weekly #CuratorBattle themes, including the popular call for "cheeky" art in June, posting a Roman marble statuette from its collections. 

Check out some highights under #BestMuseumBum in #CuratorBattle:

We raise your athlete and instead give you the bum of a drunken fish. Yes you heard me.

Made by Pamela Mei Yee Leung, it was part of a body of work which married animals and humans together to create mythological creatures with personalities. #BestMuseumBum #CuratorBattle pic.twitter.com/qUAa3NgGcG

Museums all over the world are competing over which museum has the #BestMuseumBum in its collection. Undoubtedly we have the best designer butt! #PhilipsbyAlessi #AlessandroMendini #coffeemaker #CuratorBattle pic.twitter.com/zSX60B4I0e

Museums worldwide have been sharing their #bestmuseumbum. The Minnesota Marine Art Museum's winner for best back-side has to belong to André Derain's "Les Repos" (1905). #CURATORBATTLE pic.twitter.com/rCIFJeppEk

The #MysteryObject and #BestCat themes brought out the oddities and furry renditions at museums:

This #BestCat has a special backstory! In 1965, a young girl named Amy suggested that the "Honeywell Animals" include a cat. BBDO, the ad agency in charge of the campaign, happily created this Siamese cat named Amy (gifted to her 3 years later). #CHMFromHome #CuratorBattle pic.twitter.com/xicAm44rNN

Let's do it. Feast your eyes.

We *think* this is a medieval bobbin, but it's really anyone's guess. Magic wand? Scary toilet roll-holder?

And why does it need a face? Why do they ALWAYS need faces?#CURATORBATTLE #MysteryObject pic.twitter.com/zXVmwCmyJR

Here from the John E. Conner Museum, Texas A&M University-Kingsville we have a stone face, supposedly from a Spanish mission.... pic.twitter.com/BXg2Auoxzs
