I don't play WoW myself, but Guild Wars has a character inspired by Mr. Jenkins, a Dwarf called Kilroy Stonekin, and I expect to be spending a LOT of time with the fellow this week as I put my new character through a certain quest repeatedly to gain the XP needed for Legendary Survivor. (In fact, I killed off a very promising character and ruined the chance for LS this past weekend precisely with a classic Leeroy Jenkins move. :\ )
