Squeaky Class

This prank works well with a substitute teacher, but can also work on your real teacher. You will need a couple other students to be in on the prank as well. All you have to do is, while your teacher is reading something to the class just make a quick squeaky noise. Teacher will look up, see nothing and keep reading. Then a few seconds later, someone else needs to squeak. Teacher will look up again but see nothing, keep waiting a few seconds and keep squeaking. Teacher will become annoyed but will never know where the squeaks are coming from
