This is really clever. However, I didn’t come up with it. (My blog title should actually be “Very Rarely Clever.”) I got it from my Uncle Steve, but he didn’t come up with it, either. With a little searching, it appears that a girl named Jessica Hagy came up with it. She even has it on a tee shirt, if you’re interested.
(Example: C = Sloth, D = Greed, so CD = Get Rich Quick Scams)
