At WoW Insider, we try to make it a point not to report on exploitable bugs that can break the game or give players an unfair advantage over other players. But I have to confess that there are just some bugs that are too fun to ignore. There was once this bug in Shattrath involving potions and vanity pets that probably put an unnecessary strain on the server -- but I thought it was cool that there was at least one way to have all your pets out at once.
In your time playing the game, what kind of bugs have you encountered or seen that struck you as more fun than flawed? Small orc shoulders were certainly not fun for all the orc players, but I can just imagine Alliance having a good laugh at their expense. Oh, and for the sake of not getting ourselves banned and all that, let's talk about bugs that are no longer in the game. Except, well, for the best bug ever. Don't do it! But man... it's just too darn cool.
