If you want to annoy your friends (who doesn’t?) then this teddy bear is guaranteed to make their life a misery.

You see, the Annoying Teddy Bear is its actual name and it is annoying for one simple reason - it sings Happy Birthday at you for a VERY long time.

In a high-pitched voice.

The only way to stop it singing is to wait for the battery to run out or basically destroy it completely.

And let’s be honest - who could ever destroy such a cute and cuddly toy? Have you not seen Toy Story 3?

So you’re back to the first option of letting the battery run out - however a video made by the creators of the bear shows that it will take three-and-a-half HOURS before that happens.

The bear is the subject of a Kickstarter campaign by Cornelius Malcolm Wilson and his eight-year-old daughter Mikayla, who want to make a whooping 50,000 of them.

Revealing the reasoning behind the project, Cornelius said: “We love to play jokes on people and thought what an awesome idea it would be to ship a musical teddy bear to someone that would not stop singing.”

He added: “We spent more than two years crafting the perfect annoying teddy bear that would p*** off someone you dislike or like.

“We performed a quality control test with over two dozen people to help us reach the perfect annoyance level.”

There is actually a safe mode where the bear doesn’t sing on repeat - but once you remove that safety tab, all hell will break loose.

Sleep-deprived parents may be ordering a few to take revenge on their little ones…
