Also from the art world, there was a controversy some years ago about a Danish exhibition that featured ten blenders, each containing water and live goldfish, with an invitation to the viewer that they could press the button if they wanted to. At least seven fish were pureed.
The Writing On The Wall has a large, fortified, heavily built structure surrounded by metal spikes with warnings in dozens of languages written inside. Clearly, its builders were very concerned about deterring tomb robbers. Too bad it isn't a tomb, and the warnings of danger were all too real. The structure in the story has never been built in real life precisely because of worries over it being schmuck bait.
Duncan Shiek's "Barely Breathing" is about a guy who has fallen for a woman whom he knows... he knows... will end up being bad news and likely breaking his heart and ruining his life. He knows he'll get hurt if he stays with her, but he's "thinking it over anyway." Schmuck Bait on a cracker.
The Airborne Toxic Event's "Sometime After Midnight" ends with the lines "You just have to see her/You just have to see her/You just have to see her/You know that she'll break you in two", which is definitely close to schmuck bait.
Even mentioning aloud the title of an Ear Worm song in another person's presence may constitute this trope, as they may well start to hum or sing it, thus infecting the title-sayer with the Ear Worm.
Every single time The Rock asks somebody a question, he cuts them off before they can give him an answer.
The Rock: How dare you little jabroni come on The Rock's show and not even have the class to introduce yourself? What is your name? Chris Jericho: I told you— The Rock: IT DOESN'T MATTER WHAT YOUR NAME IS!
"It doesn't matter" is something of a Catch Phrase for The Rock, to go along with his many, many others.
Another repeated schtick: "Oh god, my opponent has thrown a chair at me! HA HA, I caught it you dumb *kicks chair into the face*"
A general rule of thumb: if the resident Heel is offering to shake your hand, don't.
In a scene from Spitting Image, a retarded Ronald Reagan (the President's brain is missing) has two identical buttons right next to his bed. One reads "Nurse", the other one reads "Nuke". Guess which one he hits when his brain goes missing.
One common event in Punch and Judy shows is for Punch, on being led to the gallows, to sucker the hangman into putting his own neck into the noose because Punch "doesn't know how".
In Dino Attack RPG, the secret black operations Antarctica mission was explicitly said to be a secret mission because, if word ever got out that Mutant Dinos were invading Antarctica (not to mention that Shadow and Viper agreed to this mission behind Digger's back), the consequences would be dire. Unfortunately, Atton Rand was Wrong Genre Savvy and believed that PeabodySam wanted players to spread word about the mission, and so with the help of newly-created NPCs Cam O'Cozy and French Fries, he let Zenna spread the news that there were Mutant Dinos in Antarctica and realists were going behind the backs of idealists. Needless to say, dire consequences followed.
Jeff Foxworthy mentions such a scenario in one of his routines, where he and his family were standing in line at the movies and Jeff's mother forgot her hearing aid.
Jeff's Mom: [shouting] DON'T LOOK NOW! BUT THE MAN BEHIND US IS CROSS-EYED AS A BAT!
Jeff: [Face Palm] [to audience] One, you're embarrassed to death. And two, when someone says something like that... You gotta look.
A lot of myths claimed that gel or rubber bracelets for teens are a sexual signal and the guy who can break one from a girl would get her compelled to have sex with him. Other myths claim if the guy can take the pull tab intact from a girl's can of beer or soft drink she will kiss him, and if he can remove the lid from the can she will have sex with him. Cue the poor guy try to break with bare hands the rubber which is designed specifically to not break easily... or remove with bare fingers the factory-crimped and rolled lid from an aluminum beer cannote unless you have grip pliers for fingers and screwdrivers for nails, you would just break your nails and make a fool of yourself.
Some japanese urban legends are based around the victims taking the bait. A common one is Kashima Reiko, in which that if you read the legend, she'll appear before you. The legend itself is about a girl who got cut in half and rips other people's legs off in anger, if they knew about her or the legend based on her.
Many urban legends/games centered around summoning ghosts or spirits, like Bloody Mary or the Midnight Game, claim that dire consequences follow anyone who plays the game and doesn't adhere to a very strict formula. Many will specifically warn readers against even trying it.
In Disgaea Infinite, one path allows you to possess a Geo Symbol. If you do this, you get destroyed, triggering one of the Bad Endings.
Corpse Party: In Chapter 2, you are warned not to read the Victim's Memoirs to their conclusion. You may think "Tch! In Chapter 1 I was warned not to read that newspaper, but I had to in order to reach Chapter 1's True End. Let's take a look." Enjoy having Yoshiki realize that he's killed Ayumi and resorted to cannibalism.
