Daddy, you watch Nathan and Addie

Today while I was at a baby shower adn Michael was watching the kids, Caleb packed up a rubbermaid with "camping gear" and asked Michael to pitch the tent in the backyard. Michael said he couldn't today. Caleb then responded with "Daddy, you watch Nathan and Addie while I set up the tent." Michael laughed and said "Caleb, you're funny." Caleb responded with a completely straight face, "I'm not joking, I'm serious."
