Bigger, stronger, smarter?

I have written in the past about our little chauvinist in training. Here's our conversation from yesterday.
"Are there only man doctors?
"No, women are doctors too. Why?"
"Well, because mans are smarter than womans so only mans should be doctors."
"Why do you think men are smarter than women?"
"Well, mans are bigger, stronger and smarter than womans."
"Oh really? What about me?"
"Mom, your different. Your my mom."
