The coast guard recently stopped a boat off the California coast that was loaded with marijuana. There was so much of the stuff that they were in a quandry as to how to dispose of it. Finally they located a company on the nearby shore that had a huge kiln with a tall chimney rising high into the sky and they made a deal with the owners to burn the hemp.
For a time all went well, but suddenly a flock of birds flew right through the smoke pouring out of the top of the stack. As it turned out, these were terns that were native to the area and were endangered. So naturally, the environmentalists had to follow them to see what had happened.
And of course, they discovered that NO TERN WAS LEFT UNSTONED.
