trolley
Explanation
The Joke
The comic shows a single panel depicting a trolley (streetcar) hurtling down a track with a crowd of passengers visible through the windows. The sign on the side of the trolley reads "Philosophy Convention Sightseeing Tour." Someone shouts, "Everyone! The trolley is out of control! You have three seconds to bail out before we're going too fast!" The passengers -- all philosophers attending a convention -- are visible through the windows, presumably frozen in deliberation. The caption below reads: "By the time we realized it wasn't a thought experiment, it was too late."
The joke imagines what would happen if a group of philosophers were placed in an actual trolley problem scenario rather than a hypothetical one. The trolley problem is the most famous thought experiment in ethics, where a person must decide whether to divert a runaway trolley to save lives. Here, the philosophers are so accustomed to treating trolley scenarios as abstract thought experiments that they fail to recognize and respond to a real emergency.
The Humor
The comedy comes from the delicious irony of philosophers -- the very people who spend their careers analyzing trolley problems -- being the worst possible people to have on an actual runaway trolley. Their expertise becomes their downfall: rather than immediately jumping to safety, they presumably spend their three seconds debating the ethical implications of the situation, discussing whether consequentialism or deontology should guide their response, and questioning whether the trolley scenario is truly analogous to the canonical formulation. The caption's past-tense narration ("it was too late") confirms that their philosophical deliberation did indeed prevent them from taking practical action. It is a sharp satire of the gap between theoretical and applied knowledge.

It asks whether it is morally permissible to divert a runaway trolley to kill one person in order to save five, and has become one of the most widely discussed problems in moral philosophy.
