The teacher tells the class they are going to play a game. She will describe an object and the students will tell her what she it is.

The teacher starts, "The first object is red, round, and has a stem."

Timmy says, "I know what it is, it's an apple."

The teacher replies, "That's right, I like the way you're thinking. OK, the next item is round, has a peel, and you eat it."

Christopher says, "I know what it is, it's an orange."

The teacher says, "That's right, I like the way you're thinking."

Johnny asks, "Can I try, Teacher?"

"Yes Johnny, but keep it clean!"

Johnny sticks his hands in his pockets, feels around for a second, and says, "My object is round, hard, and has a head on it."

The teacher shouts, "Alright Johnny, go to the office!"

Johnny says, "No Teacher, it's a quarter, but I like the way you're thinking!"
