Aside - Mythbusters last night had a bit about how buttered toast seems to always fall on the buttered side.
The boys discovered that if you drop toast with your hand or knock it off the table, it's most likely to flip once and land upside down - hence, butter on your floor. Using a device that dropped toast vertically they discovered that it doesn't prefer to land on either side - may as well flip a coin. And then, of course, they took the device to the roof and proceeded to drop buttered toast all over the street. That "experiment" showed that if you push down hard when you butter your toast it can cause a bowl shape in the toast, causing it to float down like a leaf would, landing butter side UP....but of course it's not often you drop toast from a roof.
Now back to your regularly scheduled butter thread.
