Sam and I are reading Wind in the Willows together and just got to the point where Toad falls in love with cars. He is nearly run over by one, and all he can do is sit dazedly in the middle of the road and softly say "Poop, Poop" in mimicry of the car's horn. Sam has fixed on this and is wandering around the house saying the same thing, especially when sitting on her potty. Cracks me up.
