This one wasn't funny back then, but looking back on it after all these years, I can now see why all my mates had tears of laughter in their eyes at the time. This really did happen.
When I first moved to Cornwall in 1990, two friends and I moved into lodgings for a couple of years. Money was tight back then, so I decided to make a couple of gallons of peach wine from kits which were to be used as presents for Christmas. Back then, we were the biggest wind up merchants, always trying to out do each other. Once the wine was bottled, I took a couple around to the local shop next door where I used to work for sampling purposes. Everybody tried it, customers, the shop owner, even down to a local parish councillor. They loved it and asked for more.
What I didn't know was that once fermentation was complete, one of my mates had taken both demijohns into the bathroom and took great delight by peeing into both and adding a small sample of a number two to both of them.
No wonder both were reluctant to try it.
