Without pranking, April 1 is a meaningless day. Good thing there’s something as fantastic as the Annoy-A-Tron to turn it into April Fools’.

So what is the Annoy-A-Tron, and how will it make you deliver the best trick or prank on April Fools?

Available for $14.99 via Thinkgeek, it’s a three-device set that includes the Annoy-a-tron, which makes annoying beeps and other noises while being very easy to hide, which will drive your friends at home or in the office crazy while they look for it with no success. You can choose between beeps, cat meow, door knock, crickets or doorbell.

There’s also the Ringtone Annoy-a-tron, which does the same thing more or less, only with ringing and buzzing, which makes people start yelling “Whose phone is that?! Where is that phone?!”… Soon they’ll stop working and go look for it. Productivity in the office that day? Zero. Prank accomplished.

ANd the third is the Eviltron, which works more on the scary angle. It produces spooky and scary noises out of nowhere, and being unable to find it, will make things uncomfortable for those not in on the joke. You can choose between creaking, scratching noises, last breath gasping, a sinister laugh or a creepy whisper.

In all, a wide variety of ways to make people either annoyed or scared on the greatest day of all for pranksters, who just need to be the best at this and win some important office pool. The Annoy-a-tron pack is available for $14.99, but it could win you more if enough people are in on the “Best Prank” Pool, making it absolutely worth it.
