I always liked the GameFAQs jokes. Couple of years ago, when Pokemon was dominating the most requested list, the site was turned Pikachu yellow and called PokeFAQs. I think last year they went all Xbox and changed the site to Xbox green. The slow-on-the-uptake Nintendo/Square fanboys (lot of redundancies in those last few words) crapped their pants and threw a fit.
Sadly, now that GF has gone corporate, I doubt we'll see any more stuff like that. They had no change today.
