A young female teacher was giving her class of six year olds a quiz behind my back Ive got something red, round and you can eat it. what is it? she asked. an apple replied little Raymond no, said the teacher its a tomato but it shows your thinking. Ive now got something round, a greenish colored you can eat it. An apple, replied little Ian No its an onion, but it shows your thinking. Little scruffy Johnny at the back of the class says Ive got something under my desk thats an inch long, white and it has a red end. Dirty little boy, said the teacher No its a match, but it shows you were thinking, he answered.
