The cartoon 'breaks' near the end, and actual human hands are shown doing quick repair, in a nod to the talents of the animators and production crew.
First and only film appearance of the Goons.
Pappy is a lot like his son Popeye, at least where spinach (and pipes) are concerned.

Popeye sings his pappy left on the day he was born and that forty years have gone by. So that makes Popeye around forty and his father at least sixty, but likely older given his appearance.
