What is oohgle ? Is it just an advert on the tube ?
I've seen green and orangle oohgle's on the Northern Line but there are apparently purple oohgle's too ! The number one oohgle search result was this blog http://john.beynon.org.uk/what-the-heck-is-oohgle/ and the number two was oohgle itself ! http://www.oohgle.com/
