Although growing up you probably got yelled at for this a lot, one way on to make people laugh is using sarcasm. It’s hard to say just what’s so funny about it, but witty sarcasm is hilarious. You don’t want to go over the top with it and be sarcastic about everything, then people actually get tired of talking to you, but adding it in appropriate situations can be a way to get people laughing or find you interesting. This can be really tricky, you may try it later after getting familiar with your new schoolmates.
