This reminds me my favorite name while testing: "McNulla". I have seen quite a few webforms which had a regex to remove any NULL string, because of which it would not take this name as it has a "Null" string in the name.

I knew a family w/ the last name of "Null" from high school. I wonder, from time to time, if they have suboptimal experiences using the 'net.

I learned there was a place called Nan[1], when my json importer crashed to it while interpreting it as a NaN (not a number)
