Sunday Morning Potty Humour.

Child Number Two: (bursting into the kitchen with the balletic grace of a sumo wrestler) Hiya, Mum!! What's for breakfast??!!

Mother: (blearily stirring concoction in large mixing bowl, whilst waiting for coffee to brew) Bran muffins. Bran, with raisins.

Child Number Two: (deadly serious) Bummer.

Cue hysterical laughter.
