Breakfast Topic: Who's got the most HKs?

Everyone knows you can see your total lifetime Honorable Kills on your Armory profile. Most people know this number only shows up if you have at least 1,337 HKs (ha). But does anyone know who has the highest ever number of HKs? This simple question was the topic of Drifter's (US-Runetotem-H) thread on the forums; so far, the biggest anyone's found is 341,462, on a druid named Kuroma from US-Daggerspine-A. Can anyone beat that? Armory links or it didn't happen.

Update: We have a new champion already! Theplague, of EU-Frostmane H, with 411,701. Anyone want to step up to that?

Update 2: Fartzwrgoben (does that name mean anything?) of EU-Perenolda-A, a subtlety Rogue, handily tops that with an astonishing 560,878!
