Check this riddle/puzzle out. It got me confused for about half an hour trying to figure out what the answer to it was. It's so satisfying knowing the answer afterwards.
As the article states, people in the know should not tell people who are not in the know. They should only taunt them with their superior knowledge I'll be able to know if you know the answer to the riddle if you can give me the answer to this roll. PM or something to avoid having to put up fresh rolls.
