A group of men who had a spare spot on their stag party sold it on eBay to a woman they'd never met.
The girl, known only as Josie, paid £1.21 to spend the day on Ben Kolb's bachelor party, playing adventure golf in Bristol and having drinks with the boys.
A friend of the groom-to-be, Alex, explained to the Bristol Post newspaper: "We had so many people looking at the listing and lots of people contacted me - many people thought it was not real.
"I think Josie, like us just sort of did it for a laugh. She didn't come along to the whole thing, as we put the listing up a bit late really and we didn't exactly get the money back, but we all had fun and it paid for half a pint."
