I'm going to admit I just sat here for five minutes thinking up puns about you being a pair of Balls.
Well! I never heard that one before!
Actually, the joking tended to be numerical: In fact, Clara and I would have been a quartet of balls.
The kids at her school called her, naturally, Mrs. Balls. In 9th grade, some kids called me "Balls of Fire!" Always with the exclamation point.
In my 20s, in the Army, I told people my blonde hair and blue eyes were deceiving. My ancestry was Greek; my great-grandfather's name was changed at Ellis Island; immigration officials thought Testicles (pron: TEST-i-clees) wouldn't work. My memory is that that kind of a joke about my name discouraged jokes from others.
OTOH, if any group can come up with new puns and plays on the name, it'll be this one. Damn!
