We promise they are really there, one Twitter user even found a solution:
Take a look at this picture and see if you can figure out who's hugging who. HOW DID THE GUY IN FRONT GET HIS FEET TO FACE BACKWARDS???!?!
People on the internet are freaking out about this optical illusion. The prevailing theory is that it just looks like that because the guy in front is wearing athletic shorts that are white on the inside and black (or dark blue) on the sides.
