Forget Hot Dogs....
1 ratty, well loved "Doggy"
Chill at 0 degrees in freezer at least as long as it takes to brush teeth, read two stories and listen to a "mouth" story. Carefully remove from freezer, keeping "doggy" as cold at possible and place in arms of waiting child.
Serves 1 tired, too hot 3 yr old
PS. It was Callan's original idea! One night last summer in Japan he came running out of his room with doggy in hand, threw open the freezer door and tossed him in.
