i should think that from the other people's comments... only read a few though;)

haha, you probably aren't alone. :) it's from an old YouTube video. it was a song some guy made up. she probably saw it, or when south park copied it, and knew she wouldn't forget it. all cleared up? :)

None of them are, unless you make it nonsensical. Considering how much information there is about EVERYONE floating around out there these days (whether it is posted to Facebook, or public records, or stolen in a data breach from some company you have done business with, etc etc), pretty much any question about you can be researched (or socially engineered, like when some "friendly" stranger strikes up a conversation with you and gets you to disclose where you were born or talk about the dog you had as a kid). It is fake security so they don't have to actually try hard or spend money verifying who you are every time you lose your password. It seems like a good idea so most people don't complain, and it covers their ass.
