A Dutch man who underwent hip surgery two years ago has appeared in a TV interview claiming he has not been able to stop laughing ever since.
According to Huug Bosse's wife, her husband now spends his days laughing at everyone and everything and it all started when he had a hip replaced under anaesthesia in 2010.
'It appears that due to the operation, due to the anaesthesia, he was laughing more,' Mr Bosse's wife told the Dutch TV programme Man Bijt Hond as he sat roaring with laughter next to her.
While Mr Bosse did laugh before, his personality had significantly altered since the operation and he now laughed almost all the time, she claimed.
'Sometimes it starts to get really annoying all that laughing the whole day,' she said.
'When you are having a discussion and all he does is laughing, then it gets annoying.'
Mr Bosse's wife said her husband did not seem to notice the change in his demeanour, but producers from Man Bijt Hond appeared to have trouble getting a straight answer out of him.
