I'm sure you've all come across the story of the Balloon Boy - where a young boy allegedly floated away in a home-made helium balloon only to be found safe in an attic a few hours later. The unexpected denouement was that it was all a hoax.

In the video below, the delightful Rocketboomers show how the story escalated into a media sensation and earned its place in internet folklore (all in the space of a few hours).

Sit back and enjoy a few minutes of internet culture.
