If parallel universes exist, then, logically speaking, that probably means there is an alternate reality where memes don't exist. A universe where everything is just varying shades of grey (like new fast food chains), and food tastes like nothing. In this bleak reality, humans look bizarrely ageless because there is a severe lack of sunshine and vitamin D, and nobody ever laughs. In this awful universe, the only form of entertainment that exists is a single channel on a gigantic, antiquated television, which only plays static, but people watch it anyway because there's really nothing better to do. Why am I painting such a demoralizing picture of some unhappy reality that doesn't exist? To make you feel appreciative of your current station, and our wealth of memes.
