The ranger at a state park notices that the vultures are behaving very oddly.  He goes to investigate and finds the vultures on top of the body of a dead man.  But instead of eating the corpse, they're giving the man decent burial.  "Why are you doing this?" asks the ranger.   "and the vultures reply, "We were going to; but we found out that he was a lawyer.  It's professional courtesy."
