The French term "l'esprit de l'escalier," which translates literally as "the wit of the staircase," refers to those perfect, clever comebacks that you only think of after the fact. What's the best came-too-late comeback you've ever had?
Pretty much anything I've ever posted online. I'll try to make a comeback online, then think of a better comeback and thus edit my original one. I end up editing about three times, then the next day, it turns out I had an even better idea for a comeback but it was too late. One of the reasons I've stopped posting to SmackJeeves and the Homestar Runner Wiki Forum.
