The sign is created by holding your hands up in front of you with the thumbs touching and only the index fingers extended, to form a "W" shape.
Each week the show highlights signs seen at football matches, behind outside broadcasts or posed photos of people forming the W at notable locations around the world.
They also encourage celebrities to form the "W" sign, and have filmed Kevin Rudd, John Howard, Jennifer Hawkins and Kobe Bryant.
It is one of the few regularly broadcast shows apart from news programs to be filmed in Western Australia.
