Am I the only one with this sense of humor.?

I am 15, highly intelligent and go to a gifted school. I do not believe in God, and my father is a preacher. I know the Bible better than most devoted Christians. Do not try to har me your conversion methods. My friend and I, both of the same age, have a very odd sense of humor. We laugh at things that only each other say, and quite sporadic events within our lives. I never laugh at normal things such as cl clowns (because I am one and kids are easy to manipulate) and fat people falling. I will give you an example of something I laughed at hysterically. One day I was instant messaging my friends in a chat room and one of them sent a random mixture of letters like- ajsjhfhjs. So I told my friend that has my same sense of humor her mom probably was beating her head against the keyboard. Another instance of hysterical laughter was when I was coming home from wrestling practice, and my grandmother unknowingly hit the school sluts dog. These are just minor events that I can only think of on the top of my head but they truly show the only types of things I think are funny. I think about people dying just for the fun of it and find no wrong or heart-felt emotion from it. I am a unique kid and do not try to give me a bogus answer when I more than likely will degrade you for it. I want good concise answers from semi-intelligent people. I need an answer because I'm scared I'll live a boring life.
