The custom title on my profile is now a random quote from something I posted the other day. I love it, but I didn't do it. lol I'm hoping a moderator did because I think it's hilarious.
Mods used to do this to the random favored few... if you posted something particularly funny they could change your "Dis Veteran" "Mouseketeer" or "Earning my Ears" designation. You can change your own, too, in "Account Details" thus my "Errr... what?" which is just my own view of my usual cluelessness
