The comment doesn't need a big vocabulary or a complicated structure. It just needs to say the thing everyone was quietly thinking and say it fast, before anyone else beats them to it. None of this means writing a great comment is easy. It actually takes a surprising amount of instinct to know exactly how many words a joke needs and exactly where to cut it off.
The people who consistently pull it off are doing something closer to stand up comedy than typing, they're just doing it in a text box with no stage, no lighting, and no audience feedback beyond a little thumbs up counter ticking upward. So as you scroll through this list, pay attention to how short most of the winners actually are. Chances are the best one only needed a single sentence to completely derail your afternoon.
