Dixie: What can you sit on, sleep on, and brush your teeth with?
C. D. Bales: Huh?
Dixie: It's a riddle. What can you sit on, sleep on, and brush your teeth with?
C. D. Bales: I don't know.
Dixie: A chair, a bed, and a toothbrush.
C. D. Bales: What's the point?
Dixie: The point is that sometimes the answer is so obvious, you don't even realize it. It's as plain as the nose on your face.
