Dude that's funny, kids are awesome! My 8 year old brought home a "book" he had been working on at school this year. It was called "Iron Chris" and it was about how "Iron Chris" stopped a meteor from hitting New York City, complete with illustrations.
On a side note, when we got back from seeing the movie, he grabbed his Thor mask and hammer, his capt america shield and his Iron Man hand shooting thing along with the power thing that stuck on his chest and said he can be all of the avengers at the same time. Then he ran around the house beating me, his mother, and the two dogs.
