On Being a Gentleman

Max and Brooklyn were playing together in the living room, when I heard Brooklyn cry out. I ran into the living room and saw them both lying on the couch.

Me: "Max, did something happen?"

Max: "No"

Me: "Why did Brooklyn cry?"

Max: "I don't know. I was just lying down on the couch next to her like a perfect gentleman"

Where does he come up with this stuff???
