Weird Al says: WTF!?

In the first two Star Wars movies (Episodes IV and V), there were only two lightsaber colors. The Jedi used blue lightsabers, while Darth Vader used a red lightsaber. The last movie in the original trilogy, "Return of the Jedi", introduced the green lightsaber. The green lightsaber was used in this movie because a blue lightsaber didn't contrast enough against the blue sky in the fighting scenes on Tattoine.

In the prequel trilogy, both blue and green lightsabers were used by the Jedi equally. The exception is the purple lightsaber used by Mace Windu. This uniquely colored lightsaber was a request from Samuel L. Jackson, in order for him to accept the part as Mace Windu.

The peace symbol ☮ was created by Gerald Holtom in 1958. It was designed for the British "Campaign for Nuclear Disarmament". The design was created by superimposing the flag semaphore letters 'N' and 'D' (Nuclear Disarmament) onto a circle. Flag semaphore is a system of communication using two hand held flag to convey information based on what position each flag is held at. The letter 'N' in flag semaphore is created by holding both flags at an angle below the horizontal line. This forms the two angled lines on the Peace Symbol. The letter 'D' is created by holding one flag straight up and one straight down. This forms the vertical line of the Peace Symbol.

Alcohol is absorbed directly through the stomach, and in the process irritates the cells that line the organ. Alcohol also promotes secretion of additional hydrochloric acid in the stomach, eventually causing the nerves to send a message to the brain that the stomach's contents are hurting the body. The brain responds by telling the stomach to expel its contents by vomiting.

If you were to take the Earth and cut it in half along a line passing from the North Pole through Paris, and then measure the distance of the curve running from the North Pole to the equator on that circle, and then divide that distance by 10,000, you would have the traditional unit for the kilometer as defined in 1791 by the French Academy of Sciences.
