1) when some people eat asparagus, their pee smells weird;
2) when other people eat asparagus, their pee does NOT smell weird;
and Stacey and I were proud of the "fact" that our pee did not smell weird after eating asparagus, but after a bit of reading I learned that our research and consequent hypotheses were patently stupid-- what did you expect from a bunch of English teachers?-- and the fact of the matter is that everyone's pee contains asparagusic acid after asparagus is eaten, but not everyone can smell the substance; some people have a specific smell-blindness (scientifically known as a specific anosmia) to the asparagus-pee-smell . . . which leads to a philosophical question: if asparagus pee falls into a toilet, and you can't smell it, does it smell like asparagus?
