I saw that bunny a long time ago on the Runescape forums. "Help Mr. Bunny achieve world domination, post him" or something along those lines. A ton of people took a liking to it (thousands upon thousands). There were tons of spam threads made in dedication to that bunny. It was somebody on those forums, and its spread around.
the bunny is from bbs, it is as olde as the internet, but here it was started by brandon (at least this incarntaion of it) and so we will thank him, and worship the bunny...
by not conforming to us you're just conforming to the people who are simply not conforming for not conformings sake..... come on, he's a cute bunny, give him a stint... those with are still in the minority, you can still get in while it's cool instead of being a played out trend...
