Whats In The Bag

Little Johnny goes to school one day and the teacher has a brown paper bag
She reaches her hand in it and says it's round, it's got a stem, and it's got a leaf.
Little Johnny raises his hand and says it's an apple, it's an apple.
Then he says now let me give you one.
He reaches his hand in his pocket and says it's round, it's hard , and it's got a head.
The teacher says Ohh Johnny that's grose.
Little Johnny says no it's a quater but I like the way you're thinking.
