It wasn’t a “legend”. I heard it when it happened, and he has repeated the riff in a couple of shorter segments. He starts it with a comment about how women drivers are a danger to traffic because they fard in their cars while driving to work in the mornings. When asked how he knows that they are farding, he says you can see them wrinkle their noses, shift in their seats, and take their eyes off the road. It’s quite hilarious.
