I think it's something of a primal fear: inserting one's foot into the dark depths of a shoe, only to feel something that shouldn't be there.
The other morning I came downstairs, yawning, and sat down to put on my shoes and socks.
But when I inserted a foot into one of my battered sneakers, I felt something wet and lumpy and definitely foreign. I yanked out my foot instantly.
Fetching a flashlight, I peered into the shoe and saw:
Okay, 'tis the season to get little frogs in the house. I guess this guy thought he had a nice cozy cave and didn't appreciate a gigantic invader trying to squash him. I put the visitor outside.
I also put on my sandals for the time being. My sneaker had to dry.
What's the weirdest thing you've found in a shoe?
