2 1/2 was created by a kid in 2005 at Creekwood Middle School. Many have asked what 2 1/2 is, but the true responce is "Only the special may comprehend the power of
2 1/2." Only the creator can choose who the special is, and the "power of 2 1/2" means 2 1/2 is very powerful.
2 1/2 is the most powerful number, so only a few can even comprehend it.
