Lets say the dude invented something important? are you to have a better follow up question?
If your point is that they commenter is delusional, and at once over-estimating himself and under-estimating others, you should come up with a better way communicating it.
A proper punk-nosed-kid would certainly be more clever.
It adds nothing to the discussion. If the guy did something major (case#1), the discussion is over. It just makes the person asking the question look like an ass.
The other issue is that anyone who would have a reply of that caliber most likely wouldn't reply...why bother...? Thats the (#2) second case. Again, the discussion is over.
The third best case is that the guy is bluffing, and doesn't bother to answer the question. This is case (#3) but isn't really any different in motivating the discussion than case #2. Game theory says the bluff plays to look like the win, right? So just don't answer (and mimic #2).
So there are no rational replies to this question.
