When was the last time your walked away from a discussion, only to think of The Perfect Comeback hours later? Recreate the scene for us, and use your winning line.
I can't recreate the scene because this sad scene has happened so many times that they all blend together. I could however give you a bare bones scenario; I am engaged in a conversation with someone, usually not a friend or at least not a close friend, I qualify the person because why the zing in the first place, the zing comes and everyone laughs including myself because it may be a teasing zing so I join in the laughter, but I laugh on the outside while feeling silly and uncomfortable on the inside. I disengage from the conversation as gracefully as possible under the circumstances and replay the conversation a few times throughout the next few hours when later on right before bed, BOOM, it hits me like a ton of bricks, the perfect comeback redeeming my comment for all to hear. Alas it is now six hours too late and I am not calling anyone from the group to tell it over the phone. One more missed opportunity.

You mean like that episode from Seinfeld? “George, the ocean called, it’s running out of shrimp…”
Exactly, lol!
