Not seeing a plate article (although I've seen a few elsewhere), I thought I'd bring it up with thy fellow stormers and see what happens. It's not for everyone but expressive plates can be highly amusing although I admit mine's far from that, it's about not taking yerself too seriously and opening yerself up to having a laugh - possibly at one's own expense. I expect some Clarkson type (or Jeremy himself) will pull up next to me some day and shout "Get out of my way you two-eyed scottish bar steward or I'll burn your bike". He he.
So what does yours say (if anything) and why?
I offer mine and await the abuse
EU Scottish rampant lion, raised carbon lettering and a strap "Teuchtar MacDuibhshÃth Pro Rege".
My excuse; I had to get rid of the Grim Reaper plate that came with the bike and wanted to offer something that few people could make sense of.

(Demon Plates ones are slick and they offer a good service.)
Now there must be folks out there with "If you don't like my riding, stay off the pavement" (a close second choice), and other rib-tickling nuggets. Where are ye?
Starts with a R. Rrrrrrrr. Motorbike!
