It’s next to impossible not to use Upworthy-sprach in the title for something like this, so please bear with me and meet The Ross Sisters—Vicki, Dixie and Betsy—an all-singing, all dancing trio of contortionist siblings who were most famous in the 1940s. Among the amazing talents of the extremely flexible Rosses, they were able to touch their ass cheeks to the back of their heads.

“Solid Potato Salad” has already been an Internet sensation once (if not many more times), but the quality here is the best I’ve seen of this astonishing performance. They’re just singing for the first minute. Beyond that, there’s nothing to say but hit play.
