IT is more than two weeks old and is starting to get a bit cloudy, but after topping £75 last night it has become eBay's most expensive glass of piss.
The urine, passed into an Ikea tumbler after an evening of vodka and Red Bull somewhere in the Midlands, has attracted interest from the USA, Europe and Hong Kong.
Urine producer Tom Logan said: "I got up at four in the morning and I couldn't remember where the toilet was, so I just grabbed a glass out of the sink.
"I was going to chuck it when I got up and then I thought, 'no, hang on, I'll stick it on eBay'."
He stressed that people were bidding only for the urine, adding: "I'm going to wash the glass and auction it separately next week. A clean Ikea tumbler in good condition can fetch up to £42."
The previous record holder was a four day-old glass of what used to be Scrumpy Jack, which was sold to a Frenchman for £68 in the run-up to Christmas.
The recent piss-glass frenzy follows a series of record bids, including £88 for half a KitKat and a bit of old pie, £130 for a three year-old Bic pen with about half the ink still in it, and a £325 bid for a 1998 two pence piece.
Logan said he plans to freeze the urine before posting it in a jiffy bag.
