Perhaps the greatest 11 seconds to grace the internet this year was the moment a baby (safely) rolled down a hill.

It unfolded rather quickly at a rugby match in Tamworth when the baby -- within reach of a woman who we can only assume is its mother -- lost balance and began to tumble.

Realising what had just transpired, the mum jumps up and -- after a slip of her own -- safely steps in. Phew.

2018 was a year of many viral crazes, including people jumping out of moving cars to the sweet sounds of Drake. An 'In My Feelings' dance by comedian Shiggy prompted the #Kekechallenge that soon took on a life of its own....

Speaking of internet sensations, remember the time we started debating whether a male voice was saying "Yanny" or "Laurel"?

Unsurprisingly, a lot of viral moments also starred our furry friends.

There was the moment a magpie interrupted a weather broadcast in the US, or when a turkey was caught on camera chasing a boy down the street as he walked home from school.

And for something completely different (though not entirely rare) , 2018 brought us wild footage of a seal using an octopus to slap a kayaker in the face.

And then there were the kids. Our favourites?

It's really the most wonderful time of the year! Scroll up to watch the full video for more.
