I actually saw this scene take place at Comic Con one year.
This illustration is for the next edition of the Field Guide to Gomers, a catalog of comic-convention goers, (and other dorky folk) that a group of us card-carrying nerds are compiling, in the spirit of "it takes one to know one."
The first edition was hastilly put together by a group of us when exhibiting for the very first time at Comic-Con a few years ago. Despite being assembled at the last minute (while we waited for our other books to be printed) The GOMER GUIDE was a lot of fun to make and one of our hotest sellers that year. (see some pics from the 1st edition here and here)
Since then we have been able to identify and document quite a few other phylum and genus of "Gomers" (such as OBI-WANNA-BE illustrated above) so we are long over due for an expanded edition.
