ITT we will learn useless things about random topics. The person above will post a topic and you have to search it on Wikipedia, in your post you will state what you learned (if you knew everything in that (and be honest) say, "I learned nothing") And you will state another topic.
Examples:
John Doe: Picture Frames
Katamari007: I learned that they hold up pictures!
Next Topic: Dirt
OR
Bob Dole: Calculus
Katamari007: I learned nothing
Next Topic: Bananas
First Topic: Mormons
