Is this a reasonable punishment?

Hi, I'm 15.So today my mother was out at work and me and my brother were left alone. So he though it would be funny to put a rotten bannana in my backpack! Which also had my project in there. So I stayed up the entire night and when I left to go to the washroom he ran in my room and wrote "Michael WUZ HERE" and wrote hearts all over it. I worked and got barely any sleep! And on top of that He stole 3 Dollars from my desk in my room and so I decided to confront him, he replied "Oh yeah, I remember that" He laughed and went to his room. So I got devious and got Mayo, Mustard, Eggs and Tomatos and since he sleeps right next to a wall I cracked a small hole right where he usually puts his face and poured the mixture right into there and covered the hole. And for the next 3 days he was going insane and eventually moved down to the sofa. He never takes of his socks so when he went to go take a shower I poured the mixture into a bottle spray and sprayed it until it smelled horrid. He put on his socks then headed straight to sleep. The Next day he was down in tears, He stopped breathing out of his nose entirely. So I said enough is enough and I spilled the beans. He was enraged, he told my mom about what happened and got me grounded for 4 weeks! And had to let my brother sleep in my room until the smell goes away. Good thing I have my iPhone. I think my mom forgot! I want to tell my mom about the pain I had to go through on the day of the project!

Not a cool bean at all I'm afraid. You are a couple of stupid little boys and your mother must be going out of her mind living with the pair of you arguing and fighting over NOTHING at all. Rotten bananas, mustard (whose mustard by the way… Oh yes, your mother's) - holes bored in mother's house wall just to annoy a silly brother? How old are you? 7? 8? I do hope you aren't a teen because you act like a little kid. Grow up and stop wearing your mother out and also stop damaging your home and wasting your mother's storecupboard. You want sympathy? Don't make me laugh.
