I saw quite an amusing one the other day... Oregon allows you to put pretty much any combination of six characters on your plate, with spacing of your choice. Usually the characters are centred, but someone had thought to put spaces in front of their word and: " ASKEW"
Well, I liked it.
[Chalky] Tongue-in-cheek, of course. The spelling doesn't really matter, but there is definitely a distinction between Kates, Katies and the above...
[BtD] Have to agree with you on almost all of those. I would also lump Jo(h)annas in with your Joannes... Also is it just me, but girls with hyphenated names can be a bit wet, possibly deriving from an indecision on the part of their parents.
