I saw that exchange, but I don't think it fell on deaf ears. There's only so many times you can repeat the same thing before there's nothing left to say about the matter... what was he meant to reply? "OK, we'll try that right now, get your measuring kit out!"
What we got was "errr...I have no idea what you are talking about...but I am struggling to deal with the idea of real science...grannypissial auntypneumatics?...so are you saying the morphing picture isn't enough? Shit! Err..."
In fairness, I guess ones interpretation of the exchange depends on which one you respect more.
