This video is from a few years ago but it's been cycled up to the top of the feeder again and is making the rounds for some reason.
So here's the deal. A family comes home to a squirrel that is snacking on their rotting, fermenting pumpkins leftover from the holiday. Spooked by their arrival, the snacking squirrel begins to walk away...that's when his eyes start to cross and his vision becomes blurry. From eating the fermented gourds, the squirrel had become drunk.
