Stop overwriting established pages to put garbage on them. Edits like that should go on their own pages and be clearly labeled and sectioned off from the Joey stuff. Jokes are good, but they shouldn't come at the cost of information.
Anything's fine as long as it relates to Joey in some way, is clearly labeled, and doesn't overwrite information. This is a wiki about JoeysWorldTour, after all, not exactly a place you'd go expecting an ultra-moderated garbage environment. Just keep joke pages on-topic. A couple of my favorites are Chaos Joey and Joey in Super Smash Bros
