Revenge is a dish best served cold

So this Saturday night one of my roommates forgot his I.D so he had to go back to the house and get it. As soon as he got home he decided he would rather pass out than make the trek back to State Street. Unfortunately for us, he left the door unlocked. As soon as I got back after bar time, stopping at taco bell first of course, I opened the front door and noticed some things were different than when we left. Our couch was on its side and blocking all the doorways and just standing sideways in front of my roommates doorway. We also noticed that our TV was turned upside down. At first we were angry but then soon realized nothing was stolen. Haha, the next morning we got texts from the culprits claiming to be the prank crew. After a house meeting we decided we would need to retaliate and ten times better than what they did to us. Any Suggestions?
