From a reader:

3 urine references…pee, piss and urine batteries.   That, I think, is a first for an opinion piece. 

Thanks for the entertainment.

Update: From a reader:

Dear Jonah,Your reader sells you short, my friend.  In addition to the three cited references, you included two links to the evacuatory habits of various animals, including Adelie penguins.  Since birds don’t have different organs for voiding #1 and #2 (look how genteel I can be!), that makes five urine references in one piece.  If that’s not a record, God help us.
