35 year old Barry Jennings, from Manchester, England has refused to come out of his mothers womb despite repeated attempts by family, friends, neighbors and medical professionals.
The unemployed father of 2 has said that he will come out when he's 'good and ready' and not a moment earlier.
His mother has tried seeking help for her son with psychiatrists but to no avail.
"He won't have none of it", she said, "he's a very stubborn lad. Gets it from his father, he does".
It's claimed that Barry has become very attached to his surroundings and doesn't feel that the outside world is 'for him'.
"He does everything in there - east, sleeps, watches videos, shags his girlfriend's," said Barry's sister Sheila, "and he's a smoker. My poor mother has to breathe his horrible smelly smoke all day long. What a bastard!"
