10 kinds of people

"There are 10 kinds of people, those who understand binary and those who don't"

It's funny, isn't it. It's sad that it's essentially a written joke, you can't tell it any other way... but wait! THIS MORON THINKS THAT HE CAN: http://www.youtube.com/watch?v=z7GvstxiH-M

True, but don't binary/hex numbers usually have a fixed number of digits, as in 32 bit or 64 bit?
