Scrabble creator hated plural words.

No, really. He had a bias against the letter S when he created the game.

According to Plugged In, Alfred Mosher Butts--the creator of Scrabble--needed a way to figure out the distribution of letters in his new game. He decided that the New York Times served his purpose, using the frequency of letters as they appeared on the front page as the basis for how to distribute them in his new game.

Except the letter S.

Butts apparently decided that S was too easy. It could be used to pluralize words and make cheap points.

Which is true. We all know those people that add an S to the end of a triple word score that already generated, oh, 49,000 points for you, and immediately negate your genius.

Now, you can take comfort in the fact that Mr. Butts really dislikes your friends, too.
