Reminds me of an old bottom-of-the-page thing in Readers Digest where you were supposed to come up with ten body parts with three-letter names (no slang terms, so forget “ass” and “tit”).

Everybody got “arm”, “leg”, “ear”, “eye” and “toe”. A few had trouble coming up with “lid”, “gum”, “jaw”, “hip” and “rib”. Later someone decided that “fat” and “DNA” needed to be added.
