A teacher stood in front of her grade school classroom and said, "Behind
my back, I'm holding something round and hard and red. What is it."
Tommy raised his hand and said, "A red ball."
The teacher replied, "No, it's an apple; but I like the way you're
thinking."
She then said, "Now I'm holding something that's green and hard and round.
What do you think it is?"
Sarah blurted out, "A green ball!"
"No, it's a green apple; but I like the way you're thinking!"
Jimmy stood up in the back of the room and shouted, "Teacher, I'm holding
something in my pocket that's round and hard and has a head on it; what is
it."
The teacher became furious, and yelled back, "I won't stand for that kind
of language, young man! March yourself over to the principal's office."
On his way out, Jimmy walked past the teacher's desk and said, "I was
holding a quarter in my hand; but I like the way you're thinking!"
