Doonesbury by Garry Trudeau for December 23, 1972
Zonker: Have you been outside yet today? It snowed again last night. Joanie: I know. I stayed up late watching it come down. It's so beautiful here this time of year. I wish that B.D. could be home with us to enjoy the holidays. Poor B.D.! I hate to think of him all alone in the jumble over Christmas. Phred and B.D.: O, little town of Bethlehem!
