Realizing that I would need a backpack this quarter, I dug out my old Ohio State back-monkey to see if it still fit, lo these many pounds later. Surprisingly, it did. And then I tried to take it off.
Steadily mounting hysteria ensued. Unable to get a so much as a fingertip on a strap, I dashed ever-more-insanely through the house, trying to "clotheline" the backpack off on any and all surfaces.
Ever see a cat with tape on its paws? It was exactly like that.
