With a good battery, the device can easily last for 5 or 10 years, although the walls probably won't.

[A loud sound appears out of nowhere in the upper left part of the panel, around the word are many small lines going away from it and before the word there is a warning emoji. In the lower right corner Cueball is sitting in an office chair at his desk in front of his computer. He is holding his hands to his head and begins by shouting and then talking.]
⚠ Boop!
Cueball: Aaaaa!
Cueball: I heard it again!
Cueball: Where is that coming from!?
[Caption below the panel:]
It turns out living well is only the second best revenge. The best revenge is making a tiny hole in someone's wall and dropping in a battery-powered capsule that, every 6-12 hours, plays the alert sound of a USB device connecting.

I rented a room from my boss in college and he pulled this prank on me. First he hid it in the office and convinced all my coworkers to pretend not to hear it. It would switch between a creepy child's laugh to a man groaning to other random noises. I was pretty sure it was a noisemaker, but I couldn't get anyone else to admit that they could hear it so I couldn't confirm.
Then he moved it into the air vents of his house that I was renting a room in. I started to think I was developing schizophrenia since my mom suffered from it and after I confided as much in my roommate / coworker, he finally came clean and showed me where our boss hid it.
All of this to say, it's a very effective prank.
bro thats seriously fucked up
