I need a really funny prank to play on a mean teacher. Do you have any truly devious ideas?

You can start by secretly filling the teachers classroom with  balloons. When the teacher comes into the room, tell him/her that there is a strange smell in the room. He/she will quickly realise that there are balloons and will probably get furious. After a few hours the balloons will start to make lots of noise which will further enrage the teacher. Finally, you can also attach a microphone to the wall and play an annoying prank song every time the teacher turns around. This song should probably be really silly and really annoying. Your teacher will go crazy!
