Okay, so you may have heard of the problem of how to cut a piece of cake for two people so that it's fair, right? The solution is that one cuts while the other chooses which piece he gets. Simple.

What happens when you have 3 people, though? I was musing this on the way home, and to be honest I can't think of a more simple answer than "one cuts, and the other two choose their pieces". is it really that simple, or is it unfair to someone?

Thoughts?
