A good one-panel cartoon recently made the rounds online featuring two medieval peasants standing in a snowstorm. One peasant is raging about how, instead of the normal arrival of spring, they’re having what appears to be another winter: “My children will starve!”

The other peasant explains the cause of this disaster: “Two princesses up north are learning about the meaning of sisterhood.”

That’s a joke based on the plot of the Disney mega-hit Frozen, of course, which involves a princess with magical powers whose repressed emotions, released as rage, cause the realm to turn to ice. Only her sister’s love can save her and thaw out the kingdom, or something like that.
