Welcome, TMJ. Yes, your story sounds very familiar, discussing gravity with a 2yo and all. (And my DS, now 5, is still very intense, but it seems much easier to deal with these days - partly practice on both our parts, partly that he's much better able to explain these days.)

I came across a link to this T shirt the other day. No connection with the producer, but I think there's one in my future, maybe you'd like one too :-)
