If you believe in reincarnation, there is something you should know. If you make fun of a certain type of person or people, there is a good chance that you will become similar to that person or group of people in your next life. For instance, if you make fun of a minority, you may very well be a minority in your next life. If you make fun of handicapped people, there's a good chance you will be handicapped in your next life.
That's why I make fun of celebrities.
