I always laugh at the one with the dog in it where it is wrestling it's owner for a plate of sausages - walls I think. It's the one where the dog catches the smell of it and just goes loopy and it's like a scene from the film "There's something about Mary" where you see the guy wrestling around with the dog and in the end If I remember rightly he throws the dog out of the window and when it comes back up , the guy closes the window and you just see the dog sliding down the window pane.
