I don't think anyone actually gets offended by lawyer jokes. The problem is that most lawyer jokes are not really lawyer jokes, because you can replace lawyer with any other maligned profession and you have essentially the same joke.
Anyway, here are some I like:
A lawyer and an engineer were fishing in the Caribbean when they got to talking. The lawyer mentioned, "I'm here because my house burned down and everything got destroyed by the fire. The insurance company paid for everything."
"That's quite a coincidence," remarked the engineer. "I'm here because my house and all my belongings were destroyed by a flood. My insurance company, too, paid for everything."
There was a brief pause, and then the puzzled lawyer asked, "How do you start a flood?"
Farmer Bob: Hey doc, how is Lawyer Jones?
Doctor Ted: Alas, the poor fellow is lying at death's door.
Farmer Bob: Ah, there's grit for ya: at death's door and still lyin'.
