I was looking over my letters the other day and thought, "Stupid R. It's not worth anything. Why do we even have Rs. Rs should be struck from the language. I would really hate to be an R, if I were a letter."
Then, I realized....
Rs are really useful and it's often difficult to make words without Rs and other low-scoring letters. This is why they score so low. But think about it . . . Zs are a flash in the pan, one-time-use type of letter. Sure, they score a lot, but their use is very limited and quickly outlived.
I'd much rather be an R.
