Say CHEESE!!! There's a new "Cheese Challenge" that has adults throwing slices of cheese on their babies. This trend started when a twitter user named @unclehxlmes shared a video of of himself throwing a piece of cheese on his little brother's face, captioning the video "just cheesed my lil brother." It didn't take long for this video to go viral and inspire others to take part in the #CheeseChallange. Pour unsuspecting babies all around the country began getting cheesed.
