People are gluing “voice, clap, and motion-activated” stickers to random objects and it’s the perfect crime. It’s innocent. It doesn’t offend anyone. And the laughs you get from witnessing a fellow adult yelling at the hand dryer are priceless.

Created by Witty Yeti, a 50-piece pack of these stickers costs $9.29 on Amazon. “You will receive 25 Voice-Activated stickers and 25 Motion-Activated stickers. Also included are the hours of laughter you and your soon-to-be-ex-friends will have,” the sellers wrote.

So far, buyers have rated the stickers a solid 4.6/5, but the best part of their feedback is definitely the reviews. Continue scrolling to read all about their evil gags and let us know what you think of them in the comments.

Witty Yeti said the beauty of these stickers is that you can put these on anything: doors, computer monitors, towel dispensers, toasters, lamps, water fountains, coffee makers, printers, kid toys, adult toys, etc. Everything’s a prank if you’re brave enough.

In fact, they believe in their product so much, they even offer a refund to those who aren’t happy with it. “If you aren’t completely satisfied with your order, simply reach out to us through the Amazon messaging service and we will respond within 24 hours to make it right even on the weekends. We absolutely guarantee your satisfaction or your money back!” they wrote.
