The alphabet (ei bi si di i ef yi eich ai yei el em en ou pi qui ar es ti llu dllu ex guay si) was invented and put into soup in 1066 by Vanna White to satisfy the hunger of her evil Mongolian overlord Pat Sajak. In order to save time it was arranged in alphabetical order.
Originally the idea was that Alpha 5 would make a bet with Zordon that he couldn’t find 5 humans in 5 different colors. When he failed to find a smurf to be the blue ranger, Pat Sajak invaded and devoured the lot of them, including lobster-red Jason who seriously needed to be basted in sunscreen first.
First designed by Scrabble, the Alphabet was later turned into a wall of letters so Vanna could turn them on.
