My wife found a jar of Gorilla Snot under our sofa yesterday. (For those unfamiliar with Gorilla Snot, it's a product made to help guitarists hold onto their picks.) The lid wasn't very tightly sealed and the Gorilla Snot had turned into a single large Gorilla Booger (Gorilla Bogie to our UK friends). It was pretty obvious that it wasn't Ruth's glasses, even to an idiot like me.
