Lincoln, age 5:
"Mommy. I should be a scientist. Or a doctor. Because I know everything, and doctors know everything. So I should be a doctor."
"Do you know that Daddy is a doctor?"
"Yeah, that's because he knows everything."
"Also, I want to be a sword fighter... A sword fighter and a lion doctor AND a people doctor. Because people doctors know how to fix people AND lions. So that's what I'm going to do."
