I bought this at an estate sale. It was leaking out of a box labeled "Goo cities." It's been in our living room for years, but we...we don't really know what it is or...why it is. We've been using it

I asked my great grandfather about it, and he just kinda wept for a minute, stared off into space and said it belonged to his friend Jen Ex or something. He held my hand in his bony decrepit booger hooks, and I could see the years, the decades of joy, heartbreak, triumph, and pain flash across his eyes, and he was... more alive, really present, you know? than I'd seen him in years. Then he peed his pants.
