The ones that stick with me don’t normally have any comment on the legal system, but suggest lawyers are rapacious, dishonest, etc, like the shark one mentioned upthread. Nothing to do with the legal system, but the assumed lack of character of all lawyers.
And then there’s the ones that just slag lawyers as despicable:
“What do you call a hundred lawyers drowned at the bottom of the sea?”
“A good start.”
So, I should be killed because of my profession. Funee!
