Since the days following Christmas Day often feature fun with gifts opened on Christmas morning, here's a playful Flintstones comic strip from December 25, 1964. There's a lot that's fun about this comic, including Pebble's thought-balloon comment about her doll looking like Fred (apparently the writer's sly reference to the multitude of Flintstones merchandise that was put out in the wake of the show's success) and a rare appearance by Baby Puss. (The Flintstones' cat appeared a bit more in the comic strip than in the TV series, not counting the end titles. This strip was posted by Yowp at his excellent Hanna-Barbera blog in 2010. Be sure and read his entire post about the fun of a Flintstones Christmas.
