Just after Hallowe'en we got a cd by Gerry Mitchell and it is well loved in our house. He does a rendition of "How much is that doggy in the window" and the last verse is "how much is that trainer in the window". While listening to in it in the car Clover had been making all the animal noises to match the animal... but what sound does a trainer make?

"CHOO CHOO!!"
