Replying to Revenge!!!!

Ok people, here is the deal. I'm watching tv in my dorm room last night, and i hear this trickling by my door. I go open it and a so called 'friend' of mine had pissed all over my door. I chased him down, threw him on the ground and kicked him a couple times. We got into a huge argument, and his girlfriend ended up cleaning the mess. He would give me any reasoning why he would do this, and was mad at me for hurting him. So now i am really pissed. Give me some ideas for revenge, be brutal, anything goes. Thanks.
