Prime number

Torture

Universally liked. 2 is a bit of a weird member of the group though.

What a nice thing the universe has given us. The quintessential weird and unpredictable integer sequence.

Not a huge fan of these. They don't divide nicely. Someone should figure that out. That aside, I think they're fine as far as numbers go in so far as magnitude is concerned. If I have the choice between 10 and 11 I'm taking 11. It's bigger, after all. It's a numbers game.
