<human>: I have one that stands out from all of the rest.

I was 13; Me and 2 friends were at a minor league baseball game in the mediocre city of Columbia, SC. It was a diabetes benefit game that had rides and games set up out in an open area by left field, which included a bouncey-house thing and an enormous inflatable water slide contraption. At around half time, me and my dickhead friends decided it would be hilarious if we unplugged the bouncey-house while nobody was looking. Nobody was remotely near it so we figured it would just a quick laugh and nothing dangerous. My friend J pulled the plug out from a power strip on the ground, and we waited for about 5 minutes for something to happen, but nothing did. We were just turning to get back to our seats when literally hundreds of parents started screaming and running to the giant waterslide behind us. It had tipped over on its side and about 30 small children were clinging to the side as it deflated on top of them. Terrified, we fled the stadium and sat outside. A firetruck and 2 police cars showed up, so we ran and hid in the woods behind the parking lot. An hour later, we returned to the stadium and learned that everyone was okay. I laughed for so long and so hard that I was sore for days after.

Can you summarize the given text in a few sentences?
