Glenn Beck:

When I sobered up I started looking at all of the things that I believed in and decided to take everything out and only put the things back in me that I knew to be true... and then I would put it back in and then I would look at all the other things that I found were true and then I would match them and if one of them didn't fit with the other then one of them had to be wrong.

P.S. The trick is to use bubble sort.
