In the episode where Dougal takes over Pat Mustards job as a milk man, Ted and Dougal are waiting outside a house in a car for Pat Mustard to come out. Dougal has some equipment to listen to what Pat is up to and says "at this level you could hear a pin drop"...at this moment a truck drives past and deafens him and he slouches into the car seat..when the camera flicks back he is leaning back over the seat and when it comes back again, he is back to his slouching position.
