In school, there was a girl who always scribbled on my desk. I decided to get back at her. I found out she was allergic to a certain type of flower. So I put a fake flower made of paper that looked like that flower on her chair. When she sat on it and saw it, she was really scared at first thinking it was real. It made me feel a bit better after all her mean scribbling on my desk.
I know a story where a man went fishing. He was so excited when he got a big tug on his line. But when he pulled it out, it was just an old boot with a fishbone stuck in it. He had been so sure it was a huge fish. And then there was the time when a little girl dressed up her dog as a princess for a 'doggie beauty pageant' in the neighborhood. The dog looked so ridiculous but also very adorable with a tiara and a pink tutu.
My sister used to borrow my clothes without asking and return them dirty. So I took all my nice clothes and hid them when she had a big event to go to. She had to wear something old and not so nice. She learned her lesson about borrowing without permission. This was my petty revenge on her. I know it might seem a bit mean, but she had been doing it for a long time.
One funny story is about a cat that tried to catch its own tail. It kept spinning around in circles, looking so confused. Another is a little boy who put his shoes on the wrong feet and walked like a penguin all day at school. It was really hilarious.
A neighbor was constantly stealing flowers from someone's garden. The flower - loving neighbor got a bag, filled it with fake plastic snakes and hid them among the flowers. When the stealing neighbor reached for the flowers again, they got a big fright from the snakes. It was hilarious.
One story is about a student who constantly disrupted the class. The teacher, instead of yelling, made the student in charge of a special project. The student had to research and present on classroom behavior. It was a 'revenge' in a sense as it made the student understand how difficult it is for the teacher to manage a class.
I'm sorry, I don't know much about Kenneth Petty specifically. There could be many people with this name.
One revenge story in Crusader Kings 2 could be when a vassal was wronged by his liege. The vassal, after years of being oppressed and having his lands unjustly taken, managed to gather a group of loyal knights. He then launched a surprise attack on the liege's main castle during a time when the liege was away on a distant campaign. The vassal reclaimed his lands and even managed to take over some of the liege's other territories as revenge for all the years of mistreatment.
A homeowner was tired of the HOA's strict rules about exterior paint colors. So, he painted his front door a bright purple which was not on the approved list. When the HOA sent a notice, he simply replied that it was a work of art and he was expressing his freedom of expression. The HOA couldn't really do much about it as it wasn't clearly defined in the rules what constituted 'art' on a front door.
A girl's brother hid her diary. She was really angry. So, she took all of his video game cartridges and hid them in different places around the house. When he wanted to play his games, he couldn't find any of them. After a while, she told him that she would give them back if he returned her diary. He did, and she gave him his cartridges back.
Once, an IT team was trying to set up a new server. They followed all the instructions carefully, but when they turned it on, it started smoking. Turns out, they had plugged in a wrong cable. It was a hilarious yet costly mistake.
