BBC Breakfast presenters Dan Walker and Louise Minchin couldn’t hide their laughter during a segment on a killer whale who had been taught to mimic human speech.
Viewers were also left in hysterics, taking to Twitter to share their amusement.
Wikie, a 16-year old female orca, has been taught to count to three and also say English words such as 'hello', 'bye bye' and 'Amy' – her trainer's name.
Louise said: “Every time you hear it, you just can't help yourself can you?”
Dan added: “I don't know what it is about that noise, but it just does me every time.”
They listened to the sounds again, and Dan said: “It's done me in now.” As he continued to laugh, Louise asked: “Are you OK?”
Viewers also found humour in the whale’s efforts. One tweeted: “I don't think that noise is actually coming from the whale. Will someone be rushing out after the show for some new pants?”
Another tweeted: “That whale is just making fart noises - trust me, I am the mother of three boys.”
Scientists have said they now believe basic conversations with Wikie may be possible one day.
Dr Jose Abramson, from Complutense de Madrid University in Spain, said: “Yes, it's conceivable if you have labels, descriptions of what things are.
“It has been done before with a famous grey parrot and dolphins using American sign language – sentences like 'bring me this object' or 'put this object above or below the other”.
