Here is a relatively harmless violation of the Tenth Amendment: the Social Security Administration publishes lists of Americans’ favorite names for babies. Do similar data exist for other countries?
Emily, Hannah and Madison lead the pink pack for the second year running. Madison?! Do her parents fondly imagine her growing up to be a porno star, or has some other famous female Madison escaped my attention?
Much much later: “Madison” (taken from a street sign) was the name assumed by the nonhuman lead character in a movie that I never saw.
