Peter Answers is a fun web-site to help you mess around with your friends. Especially if your friends are really gullible. This site was brought to my attention by frequent Dink & Flika reader Courtney. With Peter Answers you type in a question and it will guess the correct answer to that question. For example you can type in, "What color shirt am I wearing?" When you hit enter it will guess the correct answer. However, if you do not know the secret, or if you do not believe in Peter's power it will not give you the correct answer.
Because it is not fun not knowing the trick, you can go here for the solution. Now you can fool all your friends.
