Two that have stuck in my mind, years after I saw them:
The very first personalized plate I remember seeing in-person, in Wisconsin in the late '70s, read “10SNE1” (“tennis, anyone?”)
In the ‘90s, I saw a Chevy Astro minivan with the plate “TRALFAZ” – a reference to an episode of The Jetsons, where Astro, the Jetsons’ dog, is revealed to have previously been owned by a wealthy man, who had named the dog “Tralfaz.”
That one might have been issued as “18 GPA,” with the owner putting a sticker on the plate (yes, I know, that’s likely illegal) to add the decimal point; I’ve seen something like that done on a personalized plate, to add punctuation, more than once.
Just one thing to note, about earlier questions about interspersing letters and numbers on a plate: it’s undoubtedly a state-by-state case, on what formats are allowable, and what are not.
As I noted earlier, here in Illinois, plates have to be in a numbers-then-letters, or letters-then-numbers format. But, in Wisconsin, it’s allowable for letters and numbers to alternate. My parents, who live in Wisconsin, have a personalized plate in a [LETTER]-[NUMBER]-[LETTERS] format.
Yep. The guy had put a small dot of matching paint between the spaced 1 and 8. Guess he figured either nobody would care or he could afford the fix-it ticket and fine.
