Listener Erica commented: "Perhaps an idea for a bonus ep of Four Letter Word season would be one on two-letter words: there’s an established list that Scrabble nerds end up memorizing, and it’s full of weirdness." In fact, there are TWO established lists, NASPA, the North American Scrabble Players Association, which has currently 107 two-letter words, and Collins Scrabble Words, formerly known as SOWPODS, used by the rest of the world and contains at present 127 two-letter words.

And this episode, we're going to hear all those two-letter words. If you don't agree with their Scrabbular validity, don't blame me! Some of the inclusions were a surprise, frankly!
