Chatterbox: Down to Earth

Revenge!!!!

Hi guys so, please read this story that happened to me a couple of hours ago at school.

So, UNSUSPCTINGSTRYTLLR and I are really good friends with a girl called "N". So, one day at school, we didn't see her, and we both received emails that she was really sick with the flu, and she would be out for 2 weeks. After hearing this, we were both devastated, and started emailing her back saying "Oh N! We will all miss you so much. What would we do with out you???" And "Nooooooooooo! NO N for TWO WEEKS???" And so on. Then, we kept emailing her get well soon e-cards and emails for the rest of the morning. Then, we are walking through the hallway to our next period of the day, and we hear her behind us saying "I PRANKED YOU SO BAD!!!" We turned around and there she was, laughing. We got soooooo angry and decided to get revenge. So, that is what I need your help with. We need you guys to give us good ideas to get revenge, and it has to be School appropriate. It has to be a REALLY good prank and/or revenge, because we got pranked really bad. We need your help! Please comment ASAP! All ideas are welcome! Also, please note that I don't want these prank ideas to be hurtful or mean, just friendly, funny, and harmless.

Thank you!
