"Silly humor" may give you a more balanced perspective. When you get angry and want to call someone a name, stop and picture in your mind how that word would literally look. Instead of calling the person a bitch, picture in your mind the person as a dog running around in heat. This will take a lot of the edge off your fury.
Angry people tend to feel that they are morally right, that any blocking or changing of their plans is an unbearable indignity and that they should not have to suffer. When you feel that urge, picture yourself as a god or goddess, always having your way in all situations while others defer to you. The more detail you can get into your imaginary scenes, the more chances you have to realize that maybe you are being unreasonable.
Be cautious in using humor. Do not try to "laugh off" your problems; rather, use humor to help yourself face them more constructively. Also, do not use harsh, sarcastic humor; it is just another form of unhealthy anger expression.
