Our USB Rooster Prank plays a rooster crow intermittently either every 4-8 minutes or 60 minutes. Just plug into any USB port and wait for your friends or coworkers to go crazy! #rooster #officepranks | Joker Greeting

We designed a simple USB prank that plays a rooster crowing. You can select between 60 minutes and random, with random playing between three and eight minutes. Just use an old battery pack, plug it in and turn it on, and it will start working. You can even use any old kind of battery block and get creative with an outlet to plug it in and wait, then hide it somewhere. We have a rooster, a cricket, a goat scream, and a few other sounds available at Joker Greeting. | Joker Greeting
