Which reminds me of the old story of the village idiot sitting on the wall of the local asylum watching a man picking up horse manure from the street and putting it in a cart.

"Why are you doing that?" he enquired of the man pushing the cart.

"I take it home to put on my rhubarb," came the reply.

"Eeh, you're more a daft bugger than I am, we have cream on ours", he commented shaking his head.
