The teacher noticed that Johnny had been day dreaming for a long time. She decided to get his attention."Johnny," she said, "If the world is 25,000 miles around and eggs are sixty cents a dozen, how old am I? "Thirty-four," Johnny answered unhesitatingly.
The teacher replied "Well, that's not far from my actual age. Tell me...how did you guess?"
