My Three Sons - Season 1 - Eps 9: Raft on the River
Feeling left out when Mike and Robbie decide to go camping at Gunman's Gulch, a lonely Chip uses a raft his brothers helped make in the backyard, on which he and Steve spend a night, pretending to float down the Mississippi. They are accidentally locked out when it begins to rain. Steve begins to worry when he wakes up from a nap and thinks it is way past 4am in the morning and thinks that Bub has not yet returned from his pinochle game.
