Holly crap, just when you think every weird thing has been invented here comes a new one to blow your mind.

Introducing the happiness hat, the clothing accessory that makes sure you always have a smile on your face. Either that or you will experience intense pain until you do. From their website: "Frowning creates intense pain but a full smile leaves you pain free!".

Wasn't this you were always looking for to make your life happier? :)
