An interesting Enlish class

In an Enlish class, we are going play a game. The teacher told us:" when you hear me say "Polly says", I want you to do what I say. but if I don't say "Polly says", don't to do anything,OK?"

"OK!" we said.

First, the teacher said:" Polly says stand up!"There was nobody out of the game. The teacher said:" sit down!" There were two boys out of the game. The teacher said:" Polly says sit down. raise your hands, please! Good! Polly says put your hands down. Oh, class is over. Goodbye boys and girl."

What an interesting class we had!
