[Erasmus]

I used to tell my ‘ham’ buddies, I was never an “Amateur Operator”, I was always a Professional....

I was a 'perfessional' in radio for a couple of years before I was a 'amatoor.' [Although I will confess to being a 'Charlie Bander' before I were a pro.]

We used to joke around at our dinky commercial stations by saying our station ID with the zone digit in the middle (e.g., "W9RMN). Never had the guts to do it on the air though.

Back in the '50s I was a student engineer (had a 1st Class commercial phone ticket) at the Miami University (Ohio) campus radio stations. Our carrier current station, limited to campus only, was WRMU. Our FM station, still on the air, was WMUB. We engineers joked about "This is WRUM and WBUM, your Rum-Bum stations in Oxford, Ohio." Never on the air, of course.
