frenchmen
Explanation
The comic depicts people discovering the interior of the Statue of Liberty, only to find it "filled with dead Frenchmen." One person suggests they should have put airholes in the statue and wonders if they should tell the mayor. Another person panics and insists they clean it up and tell no one, worrying about the implications if the French find out.
The caption reads: "Fun Fact: The Statue of Liberty was originally meant as a Trojan Horse."
The joke rests on the historical fact that the Statue of Liberty was a gift from France to the United States, designed by French sculptor Frederic Auguste Bartholdi with an iron framework built by Gustave Eiffel. The comic reimagines this gift as a "Trojan Horse" -- a reference to the famous stratagem from the Trojan War (as told in Virgil's Aeneid), where Greek soldiers hid inside a giant wooden horse that was presented as a gift to the city of Troy, then emerged at night to sack the city.
The humor comes from the absurd implication that France secretly filled the Statue of Liberty with soldiers intending to invade the United States, but the plan failed because nobody thought to include airholes, so all the hidden Frenchmen suffocated during the Atlantic crossing. The Americans who discover the bodies are more concerned about the diplomatic fallout ("Can you imagine the implications if the French find out?") than about the fact that France apparently attempted a military invasion.
The comic plays on several comedic threads: the long history of Franco-American relations (which have included both deep alliance and mutual antagonism), the absurdity of imagining France attempting to conquer America through a single statue, and the darkly comic image of a bungled invasion foiled by basic ventilation oversight.
