Besame mucho: four Danish couples lock lips for a potential grand prize of 10,000 kroner

If you're bored and looking for some mild entertainment this Friday afternoon, why not head on over to ekstrabladet.dk?

The Danish tabloid is currently live-streaming its latest Udfordring (challenge) in which it asks the all-important question: How long is Denmark's longest kiss?

To answer that question they have selected four Danish couples to compete in a kissing endurance competition. The rules are simple: constant contact between the lips is required, and the contestants are allowed a five-minute bathroom break after every hour.

The winning couple will bag a prize of 10,000 kroner, second place a wellness stay at Hotel d'Angleterre, and third place the questionable prize of a year's supply of lip balm from Matas.

Perhaps a supply of antibiotics would be more appropriate – a recent study found that up to 80 million bacteria were exchanged during a 'normal' kiss.

At the time of writing, the contestants had been smooching for approximately two hours and it doesn't look like a winner will be found anytime soon.
