A mate of mine back in school days entertained a young lady while on a camping trip (Swanage girls were pretty easy going in the mid 80’s by all accounts, CTBM may be able to comment)
She was reluctant to provide an appropriate ‘receptacle’ for his emissions but instead offered up her undercrackers. Which were then discarded in the bottom of his sleeping bag for several weeks before his mum, for reasons unknown, decided it would be a good idea to turn his sleeping bag inside out and put it on the line to air…….
He was presented with them, washed and dried, at tea that night in case his friend wanted them back.
