As somebody who spent way too much time creating a massive list of celebs organized by name I appreciate this series a lot lol. U and X are definitely some of the sparsest letters. As long as you’re willing to go kinda obscure Y and Z are a little easier. But then, you’re doubling down with links between them beyond letter which makes it WAY harder, so kudos on that one lol.
