Lawyers have a reputation for stretching the truth (lying). An old joke has it that when a lawyer goes to bed, he lies on his right side and then he lies on his left side, and when he dies he lies still.       
   
“By lies while alive, This attorney did thrive, And now, he lies, still” is a jocular lawyer epitaph that was printed in the Southern Literary Messenger (Richmond, VA) in March 1839. “Why is a roguish lawyer like a man who cannot sleep? Because he lies first on one side and then turns round and lies on the other, an is wide awake the whole time, and even when dead he lies still” was printed in the Bolivar (TN) Bulletin on June 30, 1866. “What do lawyers do when they die? Lie still” was printed in the Record of the Times (Wilkes-Barre, PA) on March 16, 1878. “‘What becomes of the lawyer when he dies?’ And the answer was ‘He lies still’” was printed in the 1899 yearbook of the Sunset Club (Chicago, IL).
 
The lawyer joke is also told about politicians. “What does a politician do when he dies? He lies still” was posted on Reddit—Jokes on August 5, 2022.
   
“How does an attorney sleep?”/“First he lies on one side, then he lies on the other” is one form of the joke.

Deputy Sheriff Artie O’Dea firmly believes he is going to be riding around in his own automobile before many more weeks, the result of his aptitude at solving riddles. The Chicago American has offered an automobile to the first ten people sending to it the correct answer to the riddle “What Does a Lawyer Do When He Dies?”
 
O’Dea is sure he has the right answer pegged and that he will be among the fortunate ones.
 
“What does a lawyer do when he dies?”
 
“That’s easy,” said O’Dea.

Every Riddle Given By The Riddler In The Batman, Explained

“What Does A Liar Do When He’s Dead?”
The first dead body found in The Batman is that of Don Mitchel, the mayor of Gotham City. After accusing Mitchell of lying to hide the city’s corrupt nature, the Riddler bashed his head in, cut off his thumb, and wrapped his head in duct tape to lay the clues for his first riddle.
 
The riddle’s answer is simply “he lies still,” meaning that his dead body lies motionless (“still”). It also means that even when a liar is dead, his lies continue to circulate until the whole truth is revealed.
