Dear wow,

You are such a tease!

The only thorpe I can think of is Jim Thorpe. And an octothorpe would be, perhaps, a Jim Thorpe in his eighties.

Now I'm going to have to wait for the comments to come pouring in here to deduce what an octothorpe is because I'm far to lazy to go traipsing through the archives.

Befuddled regards,
