All right, you asked for it.
Green peppers.
There is a marine animal, a species of ctenophore, which looks much like a green pepper, except that it's more regular, has rows of short cilia running up the furrows between the lobes, and is perfectly transparent - glass-clear. Just about the only way to see one in the wild is to shine a flashlight in shallow water at night and look at the beam on the bottom. When the beam passes through a ctenophore, the light refracts a bit. When annoyed, this species of ctenophore glows with a bluish-purple light.
Whenever I see a green pepper, I think of ctenophores. Then I think of their reproductive cycle. Reproduction is sexual, but ctenophores are hermaphrodites. It gets complicated. But there you go, veggies and sex.
Hey, I have to put up with this stuff all the time.
