I saw a license plate a week or two ago that said MYRRRRH.
Or maybe it was only three Rs, not sure.
Either way, I liked it. My first thought was that it represented the sound of an engine smoothly purring. Later, I thought it might be a company name, or a band name, or a character name.
I mentioned it to KTO, who suggested that this could be the start of a trend of pirate-themed Xmas stories and songs. One of the songs, for example, might be “We Three Kings of Orient Arrrr.”
