I don't think this could be accepted as trivia since it has to do beating world records and it's not actual trivia.

Well, I know that there is trivia on the site and even a few DYKG videos that reference celebrities and their loves of gaming, such as the records that Apple co-founder Steve Wonziak holds in Tetris. I wouldn't see why this isn't a similar case, but the mods can decide that.
