GOOGLE search users have today discovered that entering the search term 'Do a barrel roll' will cause the website to spin.

The prank, also known as an Easter egg, is a reference to  the classic Nintendo 64 game Star Fox 64, released in Australia as Lylat Wars.

During the game the player is advised, repeatedly, to 'do a barrel roll' when they are in danger.

The quote achieved meme status as a geek in-joke and footage of the quote has recently become inspiration for a number of humorous Youtube videos.
