What's that Skip? Little Billy's trapped down the abandoned mine shaft? And what else? Your farts are fantastic?

Kangaroos have always been a smug bunch, bouncing along as if they roo-le the animal kingdom - they will roo their mistake one day, I can tell you.

Absolutely abysmal puns aside, they now have something else to be really pleased about.

According to scientists, their farts are fighting global warming.

Thanks to a special bacteria in their stomachs, kangaroos do not emit harmful methane gas when they let off a stinker.

Australian scientists are now planning to transfer that bacteria into cows and sheep to make their flatulence eco-friendly.

It will take researchers about three years to isolate the bacteria before they can think of a way to transfer it to other animals.
