My pop, my pop (1940)

Popeye's 99-year-old father won't admit he's too old to help Popeye build a ship. Popeye tells him to build one side while he builds the other; Pappy's side is a mess. He falls asleep helping hoist the mast. While Pappy sleeps, Popeye rebuilds his side and finishes the above-decks, with a little help from spinach, of course.
