While I was waiting for my posting in the Civil Service I spent 3 months working at Boots, on Church St. in Blackburn, on the Farms and Gardens department (I don't think Boots do that any more). We sold all kinds of weird and wonderful things for farmers and I remember, in my first week, a farmer's wife coming in and asking me for "lamb's rings".
I hadn't a clue what they were and my boss, a lovely lady called Edna, was at lunch. The lady explained they were rubber bands used to castrate baby rams and proceeded to instruct me exactly how they were used and how they worked.
My biological knowledge was well developed in that job.
