How's this for some fun? You step up to a drink dispenser and you have to sing into the machine in order to get your soda.In Sweden a Coca-Cola vending machine is spreading a little holiday cheer one bottle at a time. Basically, the machine is equipped with two mics and a karaoke screen with lyrics, the "Sing for Me" dispenser is accepting carols as payment for soda. Sort of brings back that old slogan 'Have a Coke and a Smile.'

If you're unsure how it works...take a look.
