<human>: Can you condense the text into three sentences or less?

For me, this may not be the worst but the first that comes to mind. Me and 2 of my buddies were hanging out, we were about 17. Well, we were supposed to sneak out and spend the night at some girls house. So we all told our parents the old "I'm staying at so and so's house" and they told their parents they were staying at someone elses house kinda deal. So we all go to this girls house and she's like "Sorry you can't stay now" so we had nowhere to go. So we ended up sleeping in our cars in a parking lot, or trying. Well, we ended up just staying in the parking lot all night. Morning rolls around and we go back to her house after her mom left for work to hang out. Well we didn't sleep like at all so we were all tired as hell. So we decided to take a nap. Now, don't ask me why, but when I was younger and a bit more agile, I used to just randomly do ninja rolls (basically just run and do a somersault real quick and pop back up). Well, 2 of us had to sleep on couches in the living room and one of us got to sleep on the floor in her room. Being 17 we were all trying to stay in there with her. So there's blankets and pillows laid out on the floor and we all go running up the stairs to get it first. I decided "Ok time to be a badass" and I did a flying ninja flip on to the blankets. Well, I soon found out that they thought it would be funny to put a big metal jack under the blanket. (You know the game jacks, where you bounce a ball and pick up the jacks? It was one of those but about 20 times larger) So I proceed to flip and land right on this thing right on my spine. Needless to say, it was very painful and could have turned out pretty bad had that hit me in the wrong spot landing all my weight on it. I was nearly in tears for about 10 minutes it hurt so bad. SO that's mine. What's yours?
