A Derbyshire (England) woman found out she was expecting quadruplets - four days before her boyfriend was due for the snip.
Daniel Morley, 32, had booked in for a vasectomy as he and Dawn Tilt, 31, already had three children, reports the Daily Mirror.
They discovered she was pregnant four days before the op but had no idea they would be having quads until her 12 week scan.
Daniel, a steelworker, said: "It was a bombshell. I was happy and dumbfounded in equal measure. I was just speechless."
Dawn, of Castle Gresley, added: "It was such a shock. I was lying on the table and just burst into tears."
The childhood sweethearts were not on any fertility drugs, meaning they have defied 729,000-1 odds to have quads.
The babies, all healthy, are due to be delivered by caesarean section in March, nine weeks before their due date.
Now the excited parents are already thinking about the practicalities of life with seven kids.
Dawn asked: "How on earth do you manage a school run? I'm going to have five children under two, for goodness sake."
