This is our warmup item as it has appeared on a previous list. Esprit d’Escalier (literally the spirit of the staircase) is that witty comeback that you think of moments after leaving the situation in which you might have been able to use it. The staircase is a reference to your departure from the scene. This is a dreadful thing to experience, and most of the time we don’t get a chance to say the clever thing we come up with. Now, someone just needs to coin a term for the person who is so clever that he always says the right thing, without fail.
