Lamarr Chambers made headlines around the UK for his incredible mind over matter approach to his bowels.
The 24-year-old was arrested by police who suspected he had swallowed Class A drugs, with cops taking him into custody and hoping it would be only a matter of time before they would pass through his body.
They probably never expected him to refuse to use the bathroom for a whopping 47 days.
Chambers ate and drank just enough to stay alive without having to go to the bathroom and there were concerns that he could do some serious damage to his body if he kept up his stand-off.
But an expert has raised doubts about Lamarr's ability to clench.
Trish McNair, of the Primary Care Society for Gastroenterology said: "I think he may have found a way to empty his bowels, I know police were there but he may have emptied it in inside his clothes and somehow managed to hide it.
"In a young person like him, you would be able to hold on to start with, but the bowel would fill and the poo would start to dry out as it expanded.
"If you were still eating, eventually the natural reflex would occur and it would be hard to hold on and it would empty on its own accord.

"However, if you then manage to suppress that and you are not drinking the bowel would fill up with poo.
"The large bowel removes liquid and if you are not drinking, the longer you leave it the harder and drier the poo becomes and the more difficult it is push through.
"What happens is your bowel will fill up with dry poo and eventually it would push out of the body no matter how painful it may be.
"It could make you feel bloated and experience tummy pains or just being generally uncomfortable."
Chambers was supervised by police around the clock to ensure that he didn't crack one out under their nose. While holding in a shit for 47 days is impressive, it's hard to believe that he managed to go to the bathroom fully clothed and have no one smell or see it.
Doctors have also explained that his poo would have hardened and would be very painful to pass, so it'd be unlikely he'd be able to keep a straight face while trying to get it all out.
He was recently allowed to go to hospital after police dropped the motoring and drug possession charges, but in a sneaky twist, they rebooked him for supply and released him on bail so he could seek medical treatment.
