A silver carnation

Our family has a joke that is very boring but no matter what happens if we spot more than two red cars together someone says oh look a red carnation, as in red car nation, play on words that made our then small kids giggle. The joke has worn very thin and then come back as funny again over time, and we still crack the joke. This morning as I walked past this line up of silver cars and one green one I had to snap a pic, and of course share this silver carnation!
