The formula for the ''world's funniest fart'' has been revealed by scientists.

The Flatulence Report - a study commissioned by The Beano - has figured out a mathematical formula tested for 176 different noises, which range from low to high pitch, dry to wet, loud to squeaking and from short to dry.
Dr. Helen Pilcher led the research alongside the comic's ''boffins'' and sound specialists Bose Professioal, and said: ''The funniest fart is long, loud and ever so slightly wet. This gives it the potential to cause major social embarrassment.
''The research and our formula show how funny farts are. It's as simple as that. Anyone who says they've never farted or found a fart funny has pants that are probably on fire.''
The fart formula was made up of components like length, intensity, embarrassment and even the number of kids present - which is divided by age and gender of those who hear it.
Mike Stirling, editorial director of Beano Studios, added: ''We hired some genuine boffins to prove it, by helping us release the funniest fart of all time - you know, for science.''
