Whoever smelt it dealt it - but did you know that whoever smelt it could also have a reduced risk of cancer.
Scientists have discovered the smell of flatulence may have some surprising health benefits.
Experts at the University of Exeter found that in small doses, the toxic gas can help protect cells and fight illness by helping to preserve mitochondria, which drive energy production in blood vessel cells and regulate inflammation.
According to the MailOnline, Professor Matt Whiteman from University of Exeter’s medical school said: 'When cells become stressed by disease, they draw in enzymes to generate minute quantities of hydrogen sulfide.
"This keeps the mitochondria ticking over and allows cells to live. If this doesn’t happen, the cells die and lose the ability to regulate survival and control inflammation.
"We have exploited this natural process by making a compound, called AP39, which slowly delivers very small amounts of this gas specifically to the mitochondria. Our results indicate that if stressed cells are treated with AP39, mitochondria are protected and cells stay alive."
According to the Independent, Dr Mark Wood of Biosciences, at the University of Exeter, said: “Although hydrogen sulphide is well known as a pungent, foul-smelling gas in rotten eggs and flatulence, it is naturally produced in the body and could in fact be a healthcare hero with significant implications for future therapies for a variety of diseases.”
The study is published in the journal Medicinal Chemistry Communications.
