I'm always confused about the amount of the weird info/references I have picked up during my relatively short lifetime.

Ninety percent of the time, I can throw a weirdly accurate reply in five to ten seconds, usually references to popular culture of the past or pretty much anything, that I shouldn't even be aware of. I find it rather disturbing. Luckily, these days, every new bit of information just deletes something useless like German grammar.
