THE MYSTERY OF SPONGEBOB’S SEXUALITY HAS BEEN SOLVED! Rand Simberg emails a link explaining that he can’t help it:

Sponges reproduce by both asexual and sexual means. Most poriferans that reproduce by sexual means are hermaphroditic and produce eggs and sperm at different times.

Well, that settles it. I guess this won’t shed any light on the Montana election, though.
