This just reminded me of the story I heard once about a kid who didn't catch the name of his (somewhat overweight) teacher, so asked the lad next to him what it was.He wa always Piggy Watson to us
"Mr Creosote".
He proceeded to consistently call the teacher Mr Creosote for the rest of the term, which wasn't openly acknowledged or questioned by anybody involved.
Some time later, the kid saw Monty Python's Meaning of Life.
Anyway, as you were.
