My Dad was a professor of anthropology and linguistics.
He always dreaded the first day of class where you have to call out everyone's name and learn who they are.
One such student was a Phalice Long.
He calls out "Faleece Long".
She stands up and says "no sir. it's phallus long".
True story. (and one of our family faves).
He had a couple of others.

One of America's great Olympic swimmers was Misty Hyman who changed the way the butterfly was done.
Dunno what her parents were thinking.
