The Great Giraffe Challenge emerged as a viral sensation primarily on Facebook, where users shared a logic riddle involving a bedroom, animals, and a specific set of circumstances. If participants answered the riddle incorrectly, the 'punishment' was to change their profile picture to a giraffe for three days. This clever use of social pressure and curiosity turned into a massive trend, filling newsfeeds with photos of giraffes. Today, the meme is used both to reference the original 2013 riddle and as a general template for long-necked humor or the feeling of being conspicuously out of place.
