STRONG TO THE FINICH (1934)

Olive runs some kind of boarding school. She serves her charges a huge bowl of spinach, but they are less than enthusiastic about it. Popeye comes by and demonstrates the values of spinach: he feeds some to a tree, which grows huge and sprouts a variety of fruit; he feeds a hen, which lays a dozen eggs, and he eats some himself to resist a prizefighter passing by.
