Reminds me of the ol' adage about how to choose what to name your kid: stand out on the back porch and yell it three or four times at the top of your lungs. You might find that Alouiscious Finkmeister Cartwright isn't such a cool name after all.

or
"No, it HAD lettering from 19XX, but I updated it with this new script from 19XX because I etc. etc. etc."
