Why "Cranberry Flags"?
I was watching something or another on TV that was poker-related (which I've been doing a lot of recently), and there was a segment on nicknames for the different denominations of poker chips. Apparently (IIRC), at the Bellagio Hotel, their $5000 chips are red-white-and-blue (and thus referred to as 'flags') while their $25000 chips are called 'cranberries' because of their color.
At which point, I whipped out my ever-present pocket notebook and wrote down the phrase 'cranberry flags', thinking:
"I'm going to use that for *something* one of these days..."
