Love
Explanation
The Joke
A small child excitedly tells her mother, "Mommy, I'm gonna marry Billy!" The mother responds with a curious "Oh?" The child then proudly announces: "He has FOUR HUNDRED AND SEVEN Pokemon cards! I counted them!" The child is choosing her future spouse based entirely on the size of his Pokemon card collection rather than any romantic feeling.
The caption below reads: "Later, Ellen married for love, which is fleeting, instead of the solid reliability of very rare cards. She has never had a moment of joy since."
The Humor
The joke works by setting up the expectation that the punchline will be about childish naivety, but then the caption subverts this by suggesting the child's materialistic reasoning was actually the wiser approach. The narrator deadpans that marrying for love was the mistake, and that basing a lifelong partnership on a tangible asset like a Pokemon card collection would have been the sounder investment. This is a satirical inversion of the usual romantic wisdom: instead of mocking the child for not understanding love, the comic mocks adults for overvaluing it. There is also a layer of humor in how earnestly the child has counted "four hundred and seven" cards, applying rigorous due diligence to her romantic prospects in a way that parodies how adults might evaluate a partner's financial stability.
