Every time I hear someone say they're random, I think of 14 year old girls Myspace pages, and I remember why Facebook won.
I also think of computer programming classes, and how I always get way too interested in how different programming languages come up with their random numbers. Some use a digit somewhere in the computers time stamp. This website uses atmospheric noise. Now that's random.
