Something about this move makes me feel like he was bragging to somebody about how he managed to own a single letter domain, and his conversation ended up somehow here, with him doubling down on what wasn’t even a good joke to begin with.
This is purely speculative, obviously, but it just makes me think it’s him putting his money where his mouth is to save face to someone else (who is likely bemused at best)
This is one of those things that I never realized how much I wanted and needed it until I just learned of its existence
