A clever scientist (Michael Hordern) invents a machine that can listen to peoples thought brain waves but only when they are asleep. On the way home from the laboratory he finds that his bicycle has been stolen and has to get the bus. While on the top deck the machine starts to beep and he notices that the man sat beside him has fallen asleep on his shoulder. He surreptitiously peeks at the readout on his lap and discovers that the man is hoping he has corned beef and chips for tea, and one of those strawberry mousses. The End.
