What's This Shirt?

Here's a weird one: Eclypsed caught a few pictures of a fan with a homemade Wing Commander IV shirt while attending the 2006 Penny Arcade eXpo. This must be some kind of internet forum joke that we haven't seen before -- but it's a neat shirt, regardless. The Acronym Finder says FTGF means "Fight the Good Fight" -- appropriate! PAX is a major gaming convention set up by the creators of the Penny Arcade internet comic. Some of our staff attended back in 2004!
