After finding a bun placed in the oven, the 53-year-old is left perplexed and asks why she's been given brioche.

Attempting to help her mum over the line, Natalie tries to get her to say, 'hamburger bun', however Robyn instead reverts to 'roll', cueing laughter from those around her.

Following several agonising moments, finally the penny drops, and as the words 'bun in the oven' fall from her mouth, Robyn erupts with joy.

"I was relieved that she finally got it, there was a point where I thought she never would,” Natalie said.

"We'd just come back from a cruise and I think the reason she got so confused is that she thought the surprise was us bringing her back perfume from the duty-free.

"I knew mum can be a bit gullible, so I wasn't expecting her to get it right away, but she took much longer than I ever could've thought.

"I couldn't have scripted the scenario better if I tried, it was so funny.”
