The Holes
Riddle: A hole leading in, a hole leading out, we connect to a cavern that is slimy all throughout.
What are we?
Answer: It’s the nostrils—the nose. The “hole leading in” and “hole leading out” are the two nostrils, which open into the nasal cavity. That “cavern” is the mucus-lined nasal passages, which stay moist and slimy to filter and humidify air. The riddle’s accepted answer is “a nose.”
