A teacher was teaching her class. A boy came in late, his hair ruffled and his shirt torn. The teacher was angry, and asked where he had been. The boy replied "On Blueberry Hill." and sat down at his desk.
A few minutes later, another boy came in, looking as messy as the first boy had. The teacher asked him "and where have YOU been?" The second boy had the same reply as the first. "On Blueberry Hill."
The teacher was getting agitated. "Where's this blueberry hill?" she thought to herself.
Then a girl came in. "I'm the new student," she said. "Oh, and what's your name?" asked the teacher.
