The wife of an eBay seller who listed a used buggy as the item that ended his "happy carefree life" said the couple had been amazed by the advert's popularity on social media.
The current highest bid for the three-wheeler stands at more than £150,000.
Joel Andresier, from Southampton, said the buggy had been covered in "pretty much every bodily fluid known to science" by his three children.
His wife Susan said she had found the listing "hilarious".
After sharing the advert on Facebook, Mrs Andresier said she "couldn't believe how many people had shared it and looked at it, and put comments on eBay about it".
She said the couple were not expecting the high bidder to pay up for the lime green pushchair, and that her husband had "always had a very dry sense of humour".
She added: "I thought it was hilarious and I know that he doesn't mean it; it's all very tongue-in-cheek."
In the listing's description, Mr Andresier, of Sarisbury Green, said: "This was purchased against my wishes many years ago as I never wanted any children and a buggy signified my wife's intent to have children.
"We argued much and this buggy signifies everything that ended my happy carefree low cost child free life."
As well as three children, he said the couple also had a Labrador, and that he now had to "endure the school run".
"To summarize my life is over," he added.

"I have bought cars that cost less than this buggy. My dad once bought a house that cost less than this buggy.
"Anyway as you can tell I hate the buggy. I now have 3 children, and a Labrador and am forced to endure the school run where women I dont know try and discuss the price of centre parc holidays, and the benefits of the micro over the mini micro scooter. To summarize my life is over and this green albatross needs to go round some other poor sods neck.
"All of my children are now walking (often in completely the wrong direction) but someone else deserves to give this a good home. Over the years I have collected spare bits from other zombified fathers who were once full of life and I will throw these in as well."
On the comments pages of the listing, one user described Mr Andresier as a "marketing genius", while another did not see the funny side and said he was "pathetic".
Answering another comment, Mr Andresier said money was "irrelevant" and added he was glad his advert "got a smile".
However, he said if the buggy did raise enough cash he would spend it on a vasectomy.
