Baker’s next three lines are “Bum!”, “Drawers!” and “Belly!”. These come from a song by Flanders and Swann, which is called ‘P**! P*! B****! B**! D******!’. The first verse goes:
Ma’s out, Pa’s out, let’s talk rude!
Pee! Po! Belly! Bum! Drawers!
Dance in the garden in the nude,
Pee! Po! Belly! Bum! Drawers!
Let’s write rude words all down the street;
Stick out our tongues at the people we meet;
Let’s have an intellectual treat!
Pee! Po! Belly! Bum! Drawers!
