Leave GEORGE webring
Left bc I quit trying to make a good first-party iframe alternative
that conformed to my site design standards while also imparting the
message of GEORGE as intended.

Whether I join or leave, GEORGE lives on. Whether GEORGE of the JUNGLE
or CURIOUS GEORGE, GEORGE is coming and GEORGE will be known to all as
as the one true GEORGE.
