A Pharyngula poll?

Awww, my presence in Philadelphia today is acknowledged in Faye Flam's blog with a poll. I'm sure you'll all be able to give the correct answer to this one.

What is a pharyngula?

The language spoken by the aliens that Scientologists believe started life on Earth.
An advanced Kama Sutra position that requires partners to put both feet behind their heads.
A tiny parasitic catfish that lives in the Amazon and occasionally invades the human urethra.
A stage in the development of vertebrate embryos when construction of a spine begins and we all have brief possession of a "post anal tail."

Yes, as you all already knew, the correct answer is #4.
