Darn! And all this time (since 2002) I thought that I'd been the first to
make that pun. See my response to Leroy Quet in the sci.math thread
"Monogon" on June 28, 2002 at

<http://groups.google.com/group/sci.math/browse_frm/thread/3fbae661386df81b>.

The thread also explains why "digon" is preferred to "bigon"; see my post
of July 5, for example.

Cheers,
David
