One day, Mr Rodgers was in his music shop, when he heard a small scurrying sound. He looked over the top of the shop counter, and looking down, he saw a tiny little mouse.
It was obviously a girl mouse, because it was wearing a rather fetching pink tulle skirt.

"No, I'm afraid not. I've never heard of one of those. Sorry."

About half an hour later, another mouse turned up, this time wearing little blue shorts with shiny red buttons. A boy mouse, to be sure.
"Have you got a mouse organ, please Mister?", said the mouse.
"No, I'm sorry, I haven't. But it's funny, there was a little girl mouse in here asking for the very same thing, not half an hour ago."
"Was she wearing a pink tulle skirt?"
"Why yes, I do believe she was!"
