One Moonlit Night

Tony and Sam are not sure they're going to enjoy their night camping in a tent. What will happen if they wake up in the middle of the night and need some help? Dad comes up with an ingenious idea - he ties a long piece of rope from the tent to his big toe, and tells the boys to tug on the rope if they need him. But instead of the boys using the rope, an owl rests on it; a cat sits on it; and the milkman moves it out of his way.... causing dad to have a very sleepless night!
