heard today in the staffroom @ lunch time
Five year old Jimmy went home and was looking at a map with his father.
"Did you know that everyone comes from China?" he asked his father.
"That's not right," said his father. "You were born in England, Jonny was born in Australia and Mary was born here in New Zealand."
"You're wrong Daddy," said Jimmy. "Peter told me that everyone comes from their mother's China!"
(Names and countries changed to protect the innocent - but this is a true story!)
