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.
So your generalities are anecdotal?
Figures.
Libs think that way too.
A young doctor had moved into a small town and was setting up a new practice. He had a new sign painted and hung it in front of his office, proclaiming his specialties:
"Homosexuals & Hemorrhoids"
The town fathers were greatly upset with the sign and asked him please to change it. The Doctor was eager to please, so he put up a new sign:
"Queers & Rears"
The town fathers were really fuming about that one, so they demanded that the Doctor come up with a decent sign that would not offend the townspeople. So the Doctor finally came up with an acceptable sign:
"Odds & Ends"
