Okay, this is going to be a bit long, but here goes.
One time (this was back around 2011 or so), my little brother Robby and I saw this prank call video on YouTube where a guy got his local Walmart to go on lockdown because of his fake lost kid. Back then, we were really stupid and also really impressionable. So one night, Mom and Dad were going out for dinner, and told us that me, Robby, and Margaret (my big sister) were staying home alone and that we had to be on our best behavior. Anyway, after they drove off, we had our dinner and I went to my room to watch TV and I was bored as crap. So like after a while, I impulsively grabbed the cordless phone, dialed 911, and got Robby in there in my room with me.
Honestly, looking back, we were way too old not to know better than to do this. But we did anyway, thinking we could get away with it if we knew what we were doing. Well... we didn't know what we were doing. I was trying to disguise my voice to sound like a concerned father and it wasn't a very good imitation. We didn't even try to create a convincing store atmosphere in the background either.
Eventually, the dispatcher asked to speak to a Walmart employee for further information or something. Anyway, Robby said he wanted to be the employee, so I gave the phone to him and he tried to sound like a lady. He didn't sound like a lady as much as he did a kid holding his nose and speaking in a high-pitched voice. After the dispatcher asked for the "clerk's" name, she told us that she knew that this was a prank and that she was sending police to our house to arrest us. Well, me and Robby started screaming into the phone that we would never do this again and to not arrest us, but she hung up. We called back and apologized some more to no avail before hanging up and just hiding out in my room.
Soon, we heard the dogs barking outside and then there were cops banging on the door telling us to open up. I ran outside before Margaret could and there were a couple of squad cars outside and some policemen were walking around with flashlights and asking about "the guy who kept prank-calling 911 and hanging up" or something like that. At the same time, I was trying to get all these cops to leave, telling them that they had come to the wrong house, but they knew better. Margaret rushes outside and starts begging the police not to take us to jail, and in all the mess, Mom and Dad come home from their dinner date, and I remember that they looked confused and shocked and stuff. They started talking to one of the cops while Robby and I ran back in to go hide again.
To make a long story short, me and Robby were grounded for several weeks with no TV time, no internet, and no video games. I got an extra week because it was originally my idea, and neither of us were trusted around phones for quite some time afterwards. Some days I look back on this event and just wonder why we even did such a thing.
