guard
Explanation
The comic shows a scene from Jewish folklore involving a Golem -- the mythical clay creature animated to protect the Jewish community. A rabbi scolds the Golem: "The city is under attack maybe once a month! I'm not going to have him just sitting around all day." The caption below reads: "Most of the time, the Golem does laundry and dishes."
The humor comes from the mundane domestication of a fearsome mythological protector. In the original legend of the Golem of Prague, the Golem was created by Rabbi Loew to defend the Jewish community from persecution. It is typically portrayed as an awe-inspiring, powerful guardian. The comic subverts this by pointing out the practical reality: if a city is only attacked once a month, what does a giant magical clay creature do the rest of the time? The answer -- household chores -- is delightfully anticlimactic. The joke works on the same principle as stories about superheroes dealing with mundane life between crises, and it also touches on the very human tendency to find practical uses for any available resource, no matter how extraordinary.
