Kicking off its annual "24 Hours of a Christmas Story" seasonal marathon, TBS reprises (with sister channel TNT) this holiday favorite from 1983, which stars Peter Billingsley as Ralphie, the little boy who yearns to find a Red Ryder BB gun under the Christmas tree. It's about parents, little brothers, bullies, decoder rings, double dog dares and most of all, the workings of a youthful mind. The writing by Jean Shepherd (who also narrates) captures it all perfectly. Darren McGavin and Melinda Dillon also star.
