Given that Lincoln has very little understanding of superpowers, we have had a few funny conversations over the course of the movies. I, of course, answer all of his questions with guesses, but act as though my answers are proven, scientific facts. A typical question and answer session goes a little something like this:
Lincoln: Dad, how does Batman fly?
Abe: I think it has something to do with the material that his batwings are made of. They allow him to soar through the air.
Lincoln: Why didn't the Hulk make one of those so he could fly?
Abe: There wasn't enough material left to make one for someone as big as the Hulk.
Lincoln: Dad, what does that light in the middle of Ironman's chest do?
Abe: That keeps his heart going.
Abe: [Really, I have no clue] It has a magnet in it that keeps the metal from touching his heart.
Lincoln: Oh, but what does the light do?
Abe: It tells him that it is working.
Lincoln: How does the Hulk's pants stay on when he gets really big?
Abe: He's got some of those really stretchy pants.
Lincoln: Dad, the Hulk is HUGE though.
Abe: He must put on some special pants as soon as he turns into the Hulk.
Lincoln: We saw him turn into the Hulk and he didn't put on any pants, dad.
Abe: Well, he just must be wearing stretchy pants that are made for really big people.
Lincoln: I want to be the Hulk for Halloween next year.
Abe: I guess we better go to the Big and Tall store then.
Lincoln: What is the Big and Tall store?
