Years ago, I had a min-pin and also my house had someone living in the basement apartment.
One day I was in the back yard with Martian when the basement tenant came home with a 50lb bag of kibble for her dog. She was a small woman, short and slim, so from the yard what we could see was a giant bag of kibble with legs.
Martian saw it, froze, and made an inarticulate sound I assume was wonderment.
