First, there is a section at the website, MysteryFactory.com devoted to mystery jokes. Some of the jokes they present are weak (including, regrettably, many on the first page) while others worked.
Here is a sampling:
While visiting a big city, Betsy, who suspected her husband of cheating on her snuck off to visit a fortune teller of some local repute.
In a dark and hazy room, peering into a crystal ball, the mystic delivered grave news. "There's no easy way to say this, so I'll just be blunt: Prepare yourself to be a widow. Your husband will die a violent and horrible death this year."
Visibly shaken, Betsy stared at the woman's lined face, then at the single flickering candle, then down at her hands. She took a few deep breaths to compose herself. She simply had to know. She met the fortune teller's gaze, steadied her voice, and asked her question. "Will I be acquitted?"
Q: How many mystery writers does it take to screw in a light bulb?
A: Two. One to screw it almost all the way in and the other to give it a surprising twist at the end.
A police recruit was asked during the exam, “What would you do if you had to arrest your own mother?” He answered “Call for backup.”
Prosecutor: Did you kill the victim?
Defendant: No, I did not.
Prosecutor: Do you know what the penalties are for perjury?
Defendant: Yes, I do. And they're a heck of a lot better than the penalty for murder.
Q: ALL your responses MUST be oral, OK? What school did you go to?
Which gets to the notion of courtroom anecdotes and bloopers which have websites of their own. Humor in the Court comprised a series of two books put out in the early eighties. Here is a sampling of the content.
This site relates some misfires at attempted courtroom humor including this anecdote:
In the closely watched trial accusing Zimmerman of second-degree murder in the shooting death of 17-year-old Trayvon Martin, defense attorney Don West began opening statements with a knock-knock joke that met with crickets. "Knock knock. Who’s there? George Zimmerman. George Zimmerman who? All right, good, you’re on the jury," he said. And when no one laughed, he responded, "Nothing? That’s funny."
Here are several classic Gary Larson mystery-themed comic panels.
The cartoonstock.com website has over a thousand courtroom-themed comic entries and over two hundred with a mystery theme.
On a very different tack, Thomas Nast was satirizing the legal system over 140 years ago.
