A mainstay in British pop culture, Punch and Judy has found themselves in various works.
Cowboy Bebop includes a show called Big Shot with a man and a woman who report on bounty heads for bounty hunters. Their names? Punch and Judy.
V for Vendetta has this as one of the most creepy/horrible things the main character does, although he deserved it.
Neil Gaiman's short memoir-graphic novel with Dave Mc Kean, The Tragical Comedy or Comical Tragedy of Mr Punch, uses motifs from the show throughout, as well as one of the characters being the performer of an actual Punch and Judy show.
In 102 Dalmatians, Chloe and her dogs meet up with Kevin, his dogs, and Waddlesworth the parrot to see one of these shows. Hilarity and disaster ensues when spotless Oddball sees the dog puppet wearing a spotted sweater and tries to get it, and then eventually getting tied up in a bunch of balloons floating while at it. After being rescued, the puppeteer gives her the sweater.
Film - Live-Action
In the opening of The Muppet Christmas Carol, Scrooge passes by a Punch and Judy show. One of the lines in his theme is sung by the crocodile puppet before Mr. Punch hits him with his stick.
Tony Hancock co-wrote and appeared in a film called The Punch and Judy Man which features a Punch and Judy performer whose troubled relationship with his wife reflects the relationship between Punch and Judy.
The short story "Theatre of Cruelty" features a Punch-and-Judy show, only with enslaved gnomes instead of puppets. That's not the way to do it.
In Monstrous Regiment, Polly mentions having seen one or two of these in town. They were thrown out because Punch is seen using a stick on his wife that is bigger than the one Nuggan permits men to beat their wives with.
Wyrd Sisters has a scene where the playwright Hwel, after being hit by two inspirations simultaneously, attempts to write what is effectively Richard III as a Punch-and-Judy show.
Maskerade, discussing Granny Weatherwax's hatred of theatre, and resulting fascination with it, says that even the Punch-and-Judy men have stopped coming to Lancre out of terror of her glaring at them from the front row.

The Anubis Gates by Tim Powers features a more-than-usually disturbing version, presented by a more-than-usually disturbing puppeteer.
Cole Hawlings in The Box of Delights owns a Punch & Judy show, though this is something of a cover story.
A scene from The Muppet Show in which Kermit and Miss Piggy watch a Punch and Judy show is featured in An American Werewolf in London. Kermit's defense of the show's violence is immediately followed by two incredibly brutal scenes of violence.
The Joker in The Batman has a pair of clownlike brutes named this, which sets up the following joke: "By the way, have you met my associates Judy and ... Punch?" *POW*
Rocko's Modern Life features a show-within-a-show called "Meet the Fatheads", which is pretty much Punch & Judy with 1990s gross-out humor applied. The husband and wife appear to be made of snot (or maybe just fat?) and spend most of the episodes belaboring each other about said heads with parking meters and having absurd arguments.
