This has to be part of some kind of April Fools' Day joke, right?

Earlier today, Beyonce uploaded to her Instagram a brief snippet of a song about flossing, along with quick video of her and an adorable Blue Ivy (in matching sunglasses and flashing a peace sign) flossing their teeth while what sounds an awful lot like Jay Z rapping "flossin' flossin'" plays in the background. Wow.

What could this possibly mean? Some theories:

A. Beyonce has previously partnered with the White House, contributing music to the Let's Move campaign. Is a new PSA about dental health about to commence? 

B. Is this a tantalizing tease from the long-rumored upcoming Beyonce/Jay Z collaboration album? (Follow up: Will said album be for the Sesame Street set?)

C. Is this whole thing an April Fools' joke, with a yet-to-be-completed punchline?

Whatever this is, if "Flossin'" becomes 2015's #Surfbort, remember this moment.
