From a comment by ‘Tcheuchter’ on the article ‘Conundrum’, a joke (which, not having heard it previously, is worthy of repetition):
While stitching a cut on the hand of a 75 year old farmer, whose hand was caught in the squeeze gate while working cattle, the doctor struck up a conversation with the old man.
Eventually the topic got around to politicians and their role as our leaders. The old farmer said, “Well, as I see it, most politicians are ‘Post Tortoises’.” Not being familiar with the term, the doctor asked him what a ‘post tortoise’ was.
