Another one about little Johnny...
Mrs Smith the English teacher asked the pupils to think of a sentence with the word 'definitely' in it. Little Emily put her hand up.
"Tell us your sentence, Emily" said the teacher.
Emily said "The sky is definitely blue"
"No," said Mrs Smith, "that is not true. It is not definitely blue because at night it is black and at sunset it is pinkish."
"I know," said little Andrew, "sponges are definitely soft."
"No," said Mrs Smith, "that's not true. Some sponges are hard, and some animals that live in the sea are called sponges and they are quite prickly"
Little Johnny puts up his hand.
"Yes, Johnny," says Mrs Smith
"Do farts have lumps in them?" he asks
"No, Johnny, they do not" says Mrs Smith
"Then I've definitely crapped my pants"
