For anyone who has ever wondered...

I've never thought about explaining the name of this blog before. I got it from John Irving's The World According to Garp. Someone sent this to me the other day from wordspy:

undertoad noun. A form of anxiety, the chief feature of which is an overarching fear of the unknown in general and one's personal mortality in particular.

Notes:
The word undertoad comes from the phrase Under Toad which was coined by John Irving in his book The World According to Garp. In the book, the youngest child, Walt, is constantly being warned to "watch out for the undertow" while playing in the surf, but he mishears the word as Under Toad:

Garp...realized that all these years Walt had been dreading a giant toad, lurking offshore, waiting to suck him under and drag him out to sea. The terrible Under Toad.
