Yeww Farted ranks high on the scale of easy, zero damage, memorable pranks. It is a small, slim (less than 1 cm tall) device that emits one of three different fart sounds every 3 minutes. The best things are its small size, which makes it hard to find, and the adhesive back, which means it can be stuck under a chair for hands-free blaming.

Tips for success: Press the black button to turn on. You will hear a short toot to indicate the device is on. (If you don't, let us know immediately for some replacement batteries.) The batteries will last for about 3-4 days if left on. You can always replace them if you need more time. Press the black button again to turn off and save your sanity.

Contains one device, 8.3 x 4.2 x 0.9 cm Includes three 1.5V batteries (AG13) Made in China
