Live TV broadcasts are always risky, especially when you have a toddler and a baby in the house and you forget to lock your office door.

Robert Kelly discovered this life lesson in March when he appeared on BBC News to discuss the South Korean president being forced out of office. It all began when the interviewer tailed off his question and stifled a laugh, saying: "And what will it mean for the wider region... I think one of your children has just walked in," as a toddler appeared at Kelly's side.

A second child then entered the room using a baby walker before a panicked woman rushed in to try and evict the children. Kelly, a professor of politics at Pusan National University in South Korea, initially tried to continue the interview but ended up apologising repeatedly and trying to gather his thoughts. Thankfully, he managed to get back on track once his wife eventually closed the door behind them.

But that wasn't the only hilarious video being shared online this year - here are some more of our favourites.

Melbourne jogger takes reporter's question too literally

This clip went viral in January after jogger Erica O'Donnell took a TV reporter's question extremely literally. She was jogging in a Melbourne park when Seven Network's reporter Michael Scanlan stopped her to ask her thoughts on various exercise practices.

But when he asked her to spell her first and last names, she said: "F.I.R.S.T. L.A.S.T." Scanlan began laughing and O'Donnell appeared, understandably, rather embarrassed but soon saw the funny side.

Jeremy Corbyn 'walks back into the sesh'

It's the caption that makes this one.

"Hi, how you doing? We're back and we're ready for it all over again," Jeremy Corbyn said with a jolly clap of the hands and a thumbs up following June's better-than-expected General Election results for the Labour party.

But the caption, which made this tweet the 10th most retweeted on UK Twitter in 2017, interpreted it in the context of a night out. It said: "When you walk back into the sesh after throwing up."

Amtrak Snow-mo collision

This spectacular clip builds and builds and builds in slow-motion until the amazing pay off at the end. One of YouTube's top trending videos of the year with more than 12 million views, the Amtrak Snow-mo collision shows a spectacular amount of snow sent over commuters waiting on a platform by the oncoming train.

Why didn't they see the train shovelling snow further down the track and move out of the way sooner? No one knows.

Jeremy Hunt called a c**t twice in one day on TV

To the inevitable delight of many Labour supporters and junior doctors across the UK, Jeremy Hunt's name was pronounced in the worst possible way, c**t, twice in one day - and of course everyone noticed.

The BBC's political correspondent Ellie Price and Sky News' Claudia-Liza Armah both made the blunder while reporting on a cabinet reshuffle in June.

Cop's dodgy dad dancing caught on camera at Camp Bestival

Dorset Police released this clip of Special Constable Jason Cox getting into the party spirit whilst patrolling the Camp Bestival music festival, held in the grounds of Lulworth Castle in Dorset in July. Outkast's Hey Ya was his song of choice and he charmed adults and children alike.

The force said: "We hope you love 'dad dancing' Special Constable Cox as much as we do! When he was challenged to a dance off at Camp Bestival he couldn't resist strutting his stuff before being inundated with selfie requests!"

The start of Black Friday was pretty underwhelming

Some classic British humour here as, despite the huge build-up to Black Friday, TV crews in one UK PC World shop captured one man walking keenly but calmly in as the doors opened.

Not quite the stampede the reporters were expecting, then.

Little girl has best reaction to new female Doctor Who reveal

Finally, although this isn't funny as such, this little girl cheered everyone up with her reaction to Jodie Whittaker as the new star of Doctor Who in July. She watched the teaser trailer with a frown of total concentration. Then, as Whittaker was finally revealed, she screamed with delight: "The new doctor is a girl!"

Jenny Trout posted the video of her daughter on Twitter and it quickly went viral. She later said the responses were "overwhelmingly positive".
