Because everyone has ancestors, family and friends of every possible race, color, creed and national origin, and because sensitivity to such differences has reached unprecedented tenderness in recent years, it is considered rude to tell a joke that perpetuates an ethnic, social, religious, sexual, or racial stereotype. Nevertheless that still leaves plenty of material for humor, such as occupation, political persuasion, or region of origin. For example:
A Texan was boasting to an Arkansan about his ranch. "Why, my ranch is so big," he said, "that if I start out in my truck in the morning to drive around it, it’s night by the time I get home." The Arkansan nodded understandingly and said, "Yep. I had a truck like that once."
The only group detested enough to be a suitable butt for barbed humor is lawyers. Lawyers are unpopular because they’re only consulted in times of distress. Any lawyer joke is sure to draw a laugh.
"Did you hear that medical laboratories have started using lawyers instead of white rats? There are more of them and there are some things even a laboratory rat just won’t do."
Politicians are also fair game, but since approximately two-thirds of the nation’s congressional representatives are law school graduates, such jokes are really just a subset of the ’lawyer’ canon.
