This made me laugh. Improv Everywhere set up a very surreal scene in a park with eight sets of identical quadruplets all found around the New York City area. I know, right? Who knew there were so many available sets of identical quadruplets?
Apparently, identical quadruplets account for about 1 in 15 million births, though I assume the rate for non identical quads has risen massively since the advent of fertility treatments. One famous set of identical quadruplets is the Genain quadruplets, who all developed schizophrenia (Oh YEAH, that’s from Wikipedia!).
