Jeffrey Simpson (unrelated to the cartoon TV family) posts a short bit about a square watermelon found in Vancouver, which of course reminded me of the square watermelon found at an outdoor fruit store in Japan:

Marge: Oh, my goodness! Homer, those are $150!
Homer: It's worth every cent. I'm tired of fumbling with round fruit.
[the watermelon expands to its original shape and Homer accidentally drops it]
