If it walks like a duck, quacks like a duck, looks like a duck, it must be a duck

Josh: "Mommy, will you sleep with me?"
Me: "Aww, Josh....why do you want me to sleep with you?"
Josh: "Because my duck doesn't talk anymore.  He is dead.  Somebody killed him."
Me (very sad and confused that he would say this): "What happened?"
Josh: "I'm just kidding."
Me: "Well...Josh Daddy would be very sad if I didn't sleep with him"
Josh: "Well...Daddy can sleep with Waddles and you can sleep with me.  Problem solved."
