"Where do you get your ideas?" is too vague, because I suspect we all suck them in from everywhere.

Cell phone conversations are great (because we have to wonder about the other side, and try to answer for ourselves. I think there was a thing in Psychology Today about that...and why it
means talking on Cell Phones in publisc venues is kinda rude).

Your cell phone example, however, has to be the weirdest. Ick! Good luck with that story, Marshall. (I do sorta remember it). ;o)
