PS – while those crookedy little bottom teeth may seem like an evolutionary dead end, I can tell you exactly what function they serve. He uses them to pick out all the seams with surgical accuracy from any stuffed toy we give him in .053 seconds. RIP every stuffed toy we have ever brought into our house. Will prove damn useful during the stuffed animal zombie apocalypse of 2020 though.
