1) This one time a couple months ago I was driving my uncle's golf cart around, he was in the passenger seat. Some of the times he'd warn me how I got a little too close to something, except when I looked back it would be somewhat distant enough to just slip away. So anyways, we're driving and I'm in reverse and he's says "watch out now, you're getting kinda close to this truck." So, of course I turn around but I wasn't paying attention to the speed or steering but at last glance I was going too fast. This all happened in an instant. Long story short, the golf cart crashed into the truck's front and caused 600$ of damage.
2) Last year, it was in the spring and I had to check in to the Assistant Principal every day during lunch because I got caught going off campus once. (I did it like 50 times total, but only got caught once) So anyways, my alergies are killing me, my eyes blazing red from itching. And, I was known to be hanging out with my friend that got caught with weed several times. I'm staring at the assistant principal straight in the eye for like 20 seconds. That was the most akward moment I've ever been in and it was even stupider to itch my eyes.
3) I already told you guys this on another post... but passing out on a wall near a mirror was a pretty stupid idea!
4) This actually happened to my friend, but I cracked up all day from it. We're sitting in history class, and my friend is biting away at his pen like he always does. This was like the last week of school and then I just hear this snap. I turn to my friend and he's all choking... the blue ink exploded all inside his mouth and he turns and he's spitting in the trash and using his hands to scrape some out. It was mostly funny because he was laughing while this all happened. His teeth were blue for a day, but no other damage was done.
5) Last year randomly during lunch my bro's friend (Bro is older then me) comes to me and kicks me in the nuts. This started some war as it went on for about 2 weeks we'd get eachother every couple of days. He stopped once I got him while he was talking with his gf. This kindof ended it (woohoo!) the pain was too much to keep going lol.
6) Taking 4 sprays in each nostril of a nasal spray. I had a headache for 2 days straight.
7) This happened a few years ago, but I never really knew what flour smelled like besides making cookies or something. So I get close and take a huge sniff. A couple seconds later all I could see was red. Just solid red as I rush to the bathroom and try and get it out. This was one of those things that "Sounded like a good idea at the time."
8) Me and my friends like 2 years ago were playing slug wars (you get in a sleeping bag while holding it up with your hands on a trampoline while attacking eachother) and he body slammed me and I dislocated my shoulder for a day.
9) About 3 years ago I wanted to get swung around while someone held my arms. This genius decides to jump over me while I do it, while the guy holding me starts slowing down the person jumping is still in the air. I get this thought to my head "OH

!" then landed straight on my nuts. I couldn't walk for an hour.
I'm sure there's a lot more... but I can't think of anything else right now.
