If you've never then you ought

Somebody's been buying more books on Tantric sex for Helminthdale Library. At least I can't be blamed this time as I'm not allowed to order stock. Pursed lips amongst the library assistants: Minty pulls Frog to one side and points out the offending articles:

"Look at all them mucky books! They're all about that textile sex!"

Frog reckons he'll never be able to set foot in Carpet Warehouse ever again.
