Video: British twins become viral hit

Move aside Justin Bieber, there's a new YouTube sensation in town. Two 19-year-old twins from West London have taken the Internet by storm with their gap year video blog.

Finn and Jack Harries' blog JacksGap was initially set up by Jack to keep their family up to date with the pair's gap year exploits but has become a viral hit, with 1.3 million subscribers and each video getting at least a million views.
