They are some of the most famous kids on the internet and have racked up more than 815 million views on YouTube.

Charlie and Harry shot to fame on the internet after their dad uploaded a video of them.

Dad Howard posted a video of one-year-old Charlie biting his brother Harry's finger in 2007.

He uploaded it to YouTube, because he couldn't email the video to their godparents in the USA.

The video became hugely popular online and now has hundreds of millions of views.
