When you would ask the father of Chris from Reno, Nevada, something to which he thought the answer was obvious, he’d answer with jokey phrases like “Is a pig pork?” or “Is the Pope Catholic?” or “Does a bear poop in the woods?” (but with a different verb!). These sarcastic interrogatives, also known as a kind of echo question, are wonderfully discussed in an article by Charles Clay Doyle titled “Is the Pope Still Catholic?” in the journal Western Folklore. (The article is free with registration.) This is part of a complete episode.
