A Swedish woman was hit by a car on Crown Street yesterday.

Nurses at St Vincent’s emergency report she is in a stable condition but is unable to stop laughing.

The woman had just exited the Ezy Mart opposite the Clock Hotel after buying a pack of cigarettes.

She walked into Ezy Mart at around 8pm, after packaging a self-serve $3 bag of red frogs she approached the counter to buy a 25 pack of Dunhill Blues.

“She put pack on counter, she ask cost, I say 40. She started to laugh big,” said Slad the Ezy Mart employee.

Witnesses say the woman immediately bent over laughing and stumbled out onto the footpath.

Slad, the Ezy Mart employee was on hand to offer CPR.

“I thought she was drunk, turns out she was just in hysterics,” said a bystander.

Nurses at St Vincent’s confirmed the woman had no alcohol or drugs in her system.

The woman continued laughing until she stumbled onto the road, into the path of an Uber driver who, in spite of a GPS navigation system, was hopelessly lost at the time.

“I was travelling very slowly because I had no idea where I was,” said the driver.

The woman is yet to have a cigarette in Sydney.

Otherwise it can be assumed the injuries would have been more significant.

After being hit by the Uber driver the woman, mercifully, was knocked out for a few precious moments, until she regained consciousness and immediately burst into fits of laughter.

Nurses are now more concerned about the woman’s inability to stop. Eventually the condition may result in a spasm of the stomach muscle, so relaxants may have to be injected into the woman’s abdomen.

“She only stops laughing to say ‘Forty dollars! For a pack of cigarettes! Forty! It’s ridiculous!’ or words to that effect,” said Vanessa Bourne, the attending nurse.
