Lose your blues and laugh at life

Here goes, the best ever: just had a call from one of the branches to say a mouse isn't working.

"Have you cleaned it?"

I innocently asked.

"Yes. We know they don't work when they are dirty"

"So there is no dirt around the rods in the mouse?"

"Don't know."

"Well how did you clean it?"

"With a sponge and warm soapy water!"

I give up.
