Brass Band confusion

Just settling down last night, I was having a discussion with Christine, my wife about the day etc etc. Just before switching the light off to go to sleep, she said "What's that brass band in the kitchen?"

"Pardon?"

"What's the brass band...... IN THE KITCHEN"

"What you on about???"

"The brass band.... by the sink"

I wonder for a moment if my wife is going mad.... or maybe I am going mad. Visions of 25 piece Black Dyke Mills or Grimethorpe all crushed into our tiny galley kitchen!!!

"What ARE you going on about woman?"

"THE BRASS BAND! THE RING ON THE SIDE BY THE SINK!" says my dear wife.

Suddenly I get it. You see, our plumber had been round to make repairs to the sink a few days ago. I'd spotted a compression ring on the floor in the kitchen and picked it up and put it on the side.
We did laugh!
