Doug's Christmas Story - S4-E13
Continuity mistake: After Porkchop saves Beebe from drowning, it then cuts to the crowd as Patti explains the dog was originally trying to keep Beebe away from the thin ice. In this overhead shot, Beebe is wearing both of her pink boots, but in the next shot Beebe's left leg is bandaged again as it should be. (00:20:35)
