Step two: Ease your way through being strange starting with your most strict teacher. Start there because you’ll be just a little strange. Then work your way into being more strange until you’re in your most laid-back teacher’s class. By then you’ve probably gotten into being strange.
Step three: Be at least a little cool so you don’t make everybody annoyed at you, especially your teacher (that would ruin the “and not get a detention” part).
Step four: Make sure you’re having fun, because if you’re not then it’s pointless.
