French kissers aim for new record

On a day devoted to worldwide record-breaking, the French have invoked their spirit of romance and attempted the largest ever mass kiss.

While thousands of Parisians gathered for a smooch on the streets, wacky record attempts took place everywhere.

Australian weather presenter Grant Denyer pulled on 18 pairs of underpants in 60 seconds.

While New Zealander Keith Kolver broke the speed record for "zorbing" - rolling downhill in a giant balloon. He reached 52km/h (32.3 mph).
