If you're going to pay the extra money to get a custom tag, at least make it flow or make sense. If you can't make it work, just let it go. Once you're adding random letters and numbering to the end you've defeated the purpose (in my opinion). If it was about getting a tag that he could remember easily, I think the ct7 would have been problematic, especially as more grandkids started to pile up. Perhaps MRLOLO or THELOLO could have worked, if not already taken.

Of course it would be a Cybertruck owner. They're all idiots.
