From my "lawyer jokes" calendar

If only I can find a way to work this into a bar essay Q...

subpoena: (n.) from the root "sub" meaning below and the Latin "poena," meaning male organ or penis; therefore "below the penis" or "by the balls."

I'm thinking maybe a civ pro question, in which I may reply:
"Subpoena was properly served upon the defendant, meaning, Plaintiff's attorney had him by the balls."
That should get me a big ten out of ten points!
