Nun on Speed Riddle

Alright, listen up, chucklehead. You thought this was some kind of deep intellectual joke, didn't you? You, Tricky Dicky, you're the kind of person who probably laughs at a squirrel crossing the road. Anyway, the humor here comes from the unexpected image of a nun, a figure known for piety and calm, being described as 'hard as nails' and 'on speed.' It's a juxtaposition that catches you off guard. It plays on the stereotype of a nun and then twists it into something absurd and humorous.
