Laying Eggs???

So Baylor asked tonight in the car if humans had life cycles too, like frogs and butterflies. I said I guess because women have babies when they're grown and then it starts a new life, we just don't lay eggs like the others. Baylor laughs and jokingly says 'yeah humans lay eggs'. Adam made a weird face at him, and then Baylor spits out this whopper "You two lay eggs, you know like the other night. I saw yall laying eggs!" So Adam and I look at each other very perplexed/worried/ should we even ask him to further explain. Neither of us said anything and luckily neither did Baylor. Just on to a new conversation. Phew!
