One of the pranks Naruto might do is to mess with the Anbu's communication system. He could use his knowledge of chakra and some basic electronics (if we assume some modern - like elements in the fanfiction) to scramble their signals. This would make it difficult for them to coordinate with each other, and they'd be running around trying to figure out what's wrong while Naruto watches from a hiding place, having a great laugh.
The Weasley twins, Fred and George, are the most likely characters to pull pranks. They have a natural inclination towards mischief and are always coming up with new and creative ways to play jokes on their classmates and teachers. Their inventions, like the Skiving Snackboxes, are often used in pranks.
His friends could play a prank on Naruto by making him think he's finally going to be made Hokage for a day. They could set up a whole fake ceremony with everyone in the village acting like it's real. Another prank would be to swap out all of his kunai with ones that have goofy faces painted on them. And they could also make it seem like all the Ichiraku Ramen is free for a day, but when Naruto goes to eat, they tell him it was just a prank and he has to pay double.
Well, there's a fanfic where they prank Carlisle by making his office look like a disco. They put up disco balls, flashing lights and played really loud disco music. It was hilarious. Also, the prank where they switched Rosalie's beauty products for really cheap and smelly ones. Rosalie was so angry and her reaction was quite memorable.
I'm not sure specifically which 'long beard story' you mean regarding someone falling asleep. There could be many fictional or cultural stories. It might be a story where a character with a long beard, perhaps an old wise man in a fairy tale, falls asleep and then wakes up to find something amazing or changed in his world.
Yes, sometimes you can. If the stories were published on accessible websites or platforms and haven't been removed, you might be able to find them through search engines or specific archives.
Peter could play a really funny prank on the Avengers. He might use his agility to secretly attach some helium balloons to Captain America's shield. So when Cap tries to throw it, it goes all wobbly in the air because of the balloons. And for the Hulk, Peter could create a holographic image of a really cute kitten right in front of him. Since the Hulk is usually associated with destruction and anger, seeing a cute kitten would be a really unexpected and humorous situation.
In the 'Harry Potter Pranks Everyone' fanfiction, there could be some hilarious pranks. For example, a student might use a charm to make the Great Hall's ceiling show embarrassing memories of the teachers. Another prank could be to magically swap everyone's voices, so that when they talk, it comes out as someone else's voice. There could also be a prank where the Hogwarts Express gets diverted to a completely different location, and the students end up in a strange magical place full of odd creatures and unexpected challenges.
No, it is completely inappropriate. Everyone has the right to privacy, and exposing such private and potentially embarrassing situations without consent is a violation of basic privacy rights and ethical norms.
One common mischievous prank boys might do in school is swapping the teacher's textbooks on the desk when the teacher is out of the room. It can lead to a moment of confusion when the teacher comes back and tries to start the lesson.
