I think it's a mix of having glue for brains where everything seems to stick, and having the ability to quickly recall this trivia and spit it out. I think it's a genetic trait, like those handful of people who are able to recall events that happened years ago to the very date and time they happened. Lots of smart people out there. But not very many who can recall things that quickly. Fun stuff to watch these guys...These guys are amazing. They have to have photographic memories...don't they?
