BBC Breakfast hosts Dan Walker and Louise Minchin struggled to compose themselves after listening to an amusing clip of killer whales being taught to mimic human speech.
Wikie, a 16-year-old orca, has learned to count to three, say ‘hello’ and ‘bye bye’ by making noises through its blow hole.
But instead of being amazed by the whale’s impressive trick, Walker and Minchin couldn't stop giggling at the unusual noises which sounded like someone blowing a raspberry.
A chuckling Minchin said: “Every time you hear it, you just can’t help yourself can you.”
While Walker added: “I don’t know what it is about that noise but it just does me every time.”
As the clip was played again, Walker struggled to keep a straight face, saying: “It's done me in now.”
Viewers were equally tickled and shared in the hilarity on social media.
One wrote: “That whale is just making fart noises - trust me, I am the mother of three boys.”

Another posted: “Very endearing and, I'm sure, scientifically significant... but it's also a whale making imitation fart noises.”
Researchers who study the killer whales at the marine park in France have also discovered that the animals can learn a new dialect through imitation.
Orcas in the wild have been found to communicate in different dialects and accents depending on the pod they belong to.
