bomb
Explanation
This comic is a superhero parody featuring what appears to be Superman (or a Superman-like figure) confronting a villain's doomsday weapon. The villain presents "a weapon that will bring France to its knees." The bomb has multiple escalating features: it will shatter every wine glass in France, the climate is carefully fired to the temperature that converts Brie into American cheese, and other French culinary atrocities.
Superman laughs uproariously at this, finding the French-targeted food terrorism hilarious. When told "Actually, that sounds kind of mean," Superman pauses, then says "I'll get some tights to go with it" -- implying he is going to join in rather than stop it.
The final panel shows a newspaper headline: "FRANCE DEVASTATED BY CHEESE-ALTERING BOMB -- Superman converted every sophisticated French cheese into American Muenster." Superman is quoted saying "It's great on white," and the article subtitle references the "Man of Steel."
The humor operates through the subversion of the superhero genre: instead of stopping the villain, Superman finds the weapon so amusing that he helps deploy it. The joke trades on the cultural stereotype that Americans (and Superman is the most American of superheroes) find French food culture pretentious and would consider converting Brie into American cheese to be more of a public service than a crime. The escalating absurdity of the weapon -- targeting specifically French culinary pride rather than causing physical destruction -- makes the scenario silly enough that the audience sympathizes with Superman's laughter, even as the comic satirizes American philistinism toward French cuisine.
