Before Phedre Fitton died of ovarian cancer, she gave her husband one final instruction, which was to remember to water her plant in the bathroom.

After four years, Nigel Fitton was surprised and proud that we was able to keep her plant alive for so long. That's when he realized his wife managed to prank him one last time.

When Nigel was moving out of his home and into a retirement home, he and his daughter discovered that the plant he was faithfully watering every day for four years was in fact, fake.

Before Phedre died, she had replaced her plant in the bathroom with a fake one without her husband noticing, playing one final prank on her husband.

The couple's daughter tweeted about the story, saying that she could almost hear her mother chuckling with them when they discovered it.

"She was very funny. Had a cheeky sense of humour for sure," she wrote in one comment. "It's really made us all happy as a family to remember her like this."

After the story went viral on social media, their daughter, Antonia Nicol, shared a little more about her parents.

The couple met when they were 16 years old and were together ever since. "They were best friends. They worked together, traveled together and were never apart," she wrote.

She also tweeted that her father has been embracing all of the attention the story received. "My dad has just sent a message saying that it's brought a tear to his eye and he hopes it's made people happy," she said.

He enjoyed reminiscing about the prank so much he even reenacted watering the fake plants (which he still kept) for a photo he sent to his daughter.
