Believe it or not we talked about that one as recently as Jan 29 - see the Groggy Cogitations thread in "Miscellany".YeahBuddybut, (c.2002), we did not conclude the discussion. 
I'll try...On every fourth of July I camp out at Sinking Cove in Tennessee. Sinking Cove is a place that time forgot. Be careful, you might get hit in the head by a flying turkey or get run over by a white-tailed deer. Near a spring discharge on a stretch of cool moist clay you will find hundreds of Butterflies of all kinds. A beautiful sight. The Butterflies come here to get nutrients from the wet clay. The wet clay looks a lot like butter before we got into the habit of coloring butter yellow.
If my ice chest wasn't full of beer and I had some butter, I would put the butter in a pot with a lid and bury it in the clay, like they did in England in the Fourteenth Century.
