National Biathlon Championships just around the corner

You can't manufacture this type of advertising. Completely free, unprovoked and damn funny, you'd have to say. It's the inadvertent advert for Coca Cola.

Hard up for the price of trumpet, this guy from Ciudad Juárez, in the Mexican state of Chihuahua, makes do with a plastic coke bottle - and boy can he bang a beat of it.

The video of this randomer playing away with his busker mates on the street has gone viral over the past fortnight and we're sure the head honchos tucked away in Coca Cola HQ are rubbing their hands furiously in glee after watching this freebie.

Perhaps this isn't the last we'll see of the plastic-coke-bottle-playing musician. No surprises if he gets his own reality TV show off the back of the performance or else a six-figure sum for a new commercial campaign. All he needs to do is add in a 20-second prequel, downing two litres of refreshing coke and then belting out the tunes. Done deal.
