Tim Brummel, from Atlanta in the US, said he had noticed his wife Rachel Brummel had been acting a “little bit pregnant” due to food cravings and her feeling tired.
Although he’d had a vasectomy, the dad-of-three realised he hadn’t received the results from his latest check up, so decided to call up the doctors.
When he did, he was told the procedure was unsuccessful.
“She has no idea what she’s going to find out when she gets home, we’re going to add to this madness,” Brummel said, filming his three children at the dinner table.
To confirm what he thought he already knew, Brummel found out a way to do a pregnancy test without his wife knowing.
He disabled the toilet during the night so it wouldn’t flush. In the morning after his wife had been for a wee, he tested her urine sample and it came back positive.
To break the news to his wife, Brummel left flowers and a card on the table for when she got home that read: “If you ever worried that life would be a bore, put that fear aside you are now a mummy of four.”
