When I was calmed down enough, I'd have been like, "Well, Steve, I was just reading through the instruction set, interesting how it does X, Y, Z, seems like that would make it easy for it to do that thing you said wanted in a disassembler, I was just about to borrow a little simulator time to test out my theories, knock up a quick and dirty proof of concept, but since it looks like you think I can't do it, I'll just go ahead and toss these pages of notes I wrote up away because they're obviously useless." Then shut up and wait for him to crack. You have to talk to people in a language they understand.
