A vagina, a chocolate egg and the world's most f**ked proposal.

Adam Kay built a career in comedy by sharing stories from his time as a doctor. From the heartbreaking and poignant, to the funny and outrageous (or even just plain disgusting), nothing is off the table.

His 10 books — including This is Going to Hurt, his hugely popular memoir of his time in the medical profession (drawn straight from his personal diaries), which was adapted into a BAFTA-winning TV series in 2022 — have sold more than five million copies combined (no biggie).

And his This is Going to Hurt stage show, which is coming to Australia in April and May, has been seen by more than 300,000 people.

Talking to Mamamia's No Filter podcast, he shared how doctors often approach him at book signings or after his stand-up shows with their own wild tales.

"I think it's a very competitive part of medicine," he laughed.

Adam's spoken openly about removing everything from a toilet brush to a television remote from patients' bodies, and he's heard countless other 'extraction' anecdotes from fellow medical professionals.

But there's one story no one has ever beat. Ever.

Let us set the scene.

A ring, an egg, and a 'fairytale moment' gone wrong.

It was February 29, 2004. A leap day, which, according to ancient Irish tradition, is a day on which women propose to their male partners.

So one woman decided to do just that in her own special way.

Only things didn't quite go to plan.

The story begins with the woman wandering into the emergency department, with her boyfriend in tow. Now, this man has no idea of the situation he is about to confront.

The woman sees Adam and asks for his expert doctoring assistance.

There's something stuck inside her vagina, but she refuses to give any indication what exactly that something is.

So, in Adam goes with his sponge-holding forceps to gently extract the blockage.

I'm sure you can see where this is going…

Out comes the plastic egg from inside a Kinder Surprise chocolate — the one that usually contains a small toy.

"I am about to chuck it in the bin," Adam recalled. "She says, 'Oh no, no! Don't do that! He needs to open it.'"

"So I passed him a pair of latex gloves, sandblasting the last remnant of romance from this situation."

Most people would have called it quits and trudged home around this time. But this woman was determined.

With his gloves now on, he opened the Kinder egg, only to find a ring inside.

"This particular patient of mine decided that she was going to take this opportunity to propose and put an engagement ring inside the plastic bit from inside the Kinder Egg," Adam explained.

Yep, you heard that right.

She went ahead and popped the question anyway.

In a hospital.

With an egg that had been inside her vagina just minutes ago.

No, it wasn't the romantic boudoir proposal she'd had in mind, but love is love, we guess…

He said yes, and the couple get engaged right there, in cubicle three.

Who says romance is dead, hey?
