Prince William, 40, had been visiting NHS staff at Ipswich Hospital when he made the surprise call to a group of six form students – cracking jokes and leaving them in stitches.
In a video posted on TikTok by 18-year-old Hannah Wickison, Prince William appears on a pupil’s phone screen while sitting with one of their mothers.
According to Perthnow, the future king made the call while visiting Ipswich Hospital and was seen with East of England Ambulance Service delivery manager Kerry Gaskin, who made cupcakes for the informal royal visit.
The video shows the children, from Colchester in Essex, laughing with the prince.
During the call, the Prince says: ‘Who’s the guy, to the corner?’ and points to the pupil as the others laugh and the camera focuses on the bashful boy, who giggles and bows his head.
Amid the giggles, William asks: ‘Are you guys doing any work?’ to which the chorus of pupils replies: ‘No!’
The pupil’s mother chimes in and tells the children: ‘You should be’, before they inform her they’re on their lunchbreak.
Hannah was sitting with pals when one boy got a call from his ambulance worker mum Kerry.
”A friend’s mum called him whilst he (William) was visiting her at work and he was on the other end of the line,’ Hannah said.
‘We were all just so shocked and didn’t expect it, completely speechless.
‘We were just laughing at everything he was saying as we didn’t know what to say.
‘He asked us if we were friends with Ed Sheeran as one of our friends has red hair.’
William made another joke to his eager audience, telling Kerry’s son: ‘Your mother’s feeding me her cakes.
He then holds up a cupcake to the camera, quipping: ‘They’re not very good!
The children then burst into laughter as the prince adds: ‘I’ve told her she wouldn’t win Bake Off.
‘Hannah said all the kids were speechless after the call.
‘It was just really unexpected, the things he was saying — you just don’t really think they’ll have a joke with you, I guess,’ she said.
‘We ended the call and had some lunch left and we all just sat there in silence, completely speechless, processing everything.
‘Some people didn’t think it was real and they thought it was a filter of him.
‘Yeah, I won’t forget that for a long time.’
