So, Noah has this thing for Iron Man. He's got a costume, plus a couple shirts handed down to him, so he's curious this intimidating-looking superhero. He asks, "Who is Iron Man? Is he a bad guy?" (He's also got a different thing about "bad guys".) His sisters assure him that Iron Man's not real, but just a machine. I mention that no, in the story, the Iron Man costume is made by a man named Tony Stark, but it's all make-believe.
At this point, they were surprisingly excited at the idea that this character should have a normal, real name. Then one of them remembers that our mailman's name is Tony. "Wow! Our mailman's Tony and Iron Man is Tony! I think our mailman is Iron Man!!"
Makes sense to me. I mean, how many men could possibly be called Tony and have the second word of their job title be "Man"?
