Nope. They haven't done any screwing which came to my attention. Does not mean they do not do it, but they must be more discreet in it then. How many "Doctors, Electrical Engineers and Physicists" jokes could you recall? Pretty few, I bet. And how many lawyer jokes? And while the lawyers easily outnumber the physicists and EEs, they do not outnumber doctors that easily. Therefore provoking, and providing material for, jokes must be something specific to the lawyers, as opposed to the other professions you listed. The same is reflected in the degree of trust and respect commanded by different professions. Lawyers and journalists are at the bottom of the heap, IIRC.
