Little Johnny was sitting in class one day, when his teacher held up
a bag, and asked the class to guess what was inside.
"Here's a hint," she said. "It's a fruit, and it's crunchy and red."
Johnny's hand shot up. "It's an apple!" he declared.
"Good job, Johnny. I like the way you think."
"Thank you, teacher. Now I have a question for you. There's something
in my pocket that's hard and round, with a head on one end. What is
it?"
"That's it, Johnny," yelled the teacher. "Go to the office."
"It's a quarter, teacher. But I like the way you think."
