Son : "I was top of the class last week."
Mum : "How did you manage that?"
Son : "I managed to answer a question about elephants."
Mum : "What question?"
Son : "Well, the teacher asked us how many legs does an elephant had, and i said five."
Mum : "But that wasn't right."
Son : "I know, but it was the nearest anyone got."
Mum : "Huh???"
