You don't even entertain the hypothetical, or dignify it with an answer, for the sake of playful back-and-forth?
That's a tad bit annoying. It's not a competition; not sure if you realized, but you don't have to be the grounded, logical mind all the time. It feels a tad condescending when you can't even answer a freaking playful, joking question without coming off like I'm stupid for even entertaining the possibility.
“…Judge not what a man has done, but judge what he could have done if he was a different bloke altogether. For art thou a leper? And a leper can changeth his spots…” --Rudy Wade, Misfits (Series 4, Episode 8)
