There's a reason they're called silent but deadly - according to one doctor, really stinky farts can theoretically make you go blind. You can watch the video here:
OK, so obviously this only happens in very extreme cases - but nonetheless, it might make you think twice before letting one rip.
Dr Anthony Youn, a holistic plastic surgeon from Michigan, America, was responding to a comment by someone who claimed to have gone blind for three minutes after farting.
Turns out, there could be a reason for the commenter's alleged sight loss, and the medical professional was on hand to explain the science behind the phenomenon.
In the video, he says: "Although this is very unlikely, if the gas you pass is extremely pungent, it could contain large amounts of hydrogen sulfide.
"Studies show that hydrogen sulfide is very effective at reducing blood pressure.
"If [a fart] reduces blood pressure to the central retinal artery, your silent but deadly toot could theoretically make you go blind.
"So be careful if you're making a lot of bubbles in your bathtub!"
The clip has garnered 3.1 million views on TikTok, and while some people were shocked at the revelation, others weren't all that surprised.
One commenter: "I've been around others who passed gas and I almost threw up, definitely got dizzy... so I can see going blind from someone else as a possibility."
Another joked: "Taco Bell is going to have a lawsuit on their hands," while a third added: "OMG my husband's going blind!"
While we're on the weird and wonderful topic of farting, it's not just stinky ones that cause some damage.
A former reality star who made $200,000 (£148,000) from farting in jars has announced her retirement, after she was rushed to hospital for squeezing out one too many.
Steph Matto, 31, from Connecticut, recently found herself in A&E with symptoms of a 'heart attack' after experiencing shooting pains in her chest.
Concerned doctors performed blood tests and an electrocardiogram (EKG/ECG) but later told the 90 Day Fiancé star that the symptoms were actually caused by excess gas from her frequent diet of beans, eggs and banana protein shakes.
Speaking about her hospital visit, she said: "I didn't tell my doctors about the farting in the jar but I did tell them about my diet.
"It was made clear that what I was experiencing wasn't a stroke or heart attack but very intense gas pains.
"I was advised to change my diet and to take a gas suppressant medication, which has effectively ended my business."
