About
Cillit Bang is the name given to the range of cleaning products created by Reckitt Benckiser. In 2005, Cillit Bang’s new advert for the UK was aired, featuring the charisma-less Barry Scott, with his cheesy catchphrase “Bang! And the dirt is gone.”, and his “penny test”.
Soon afterwards, many video spoofs and remixes (many influenced by JAKAZiD's original remix) started appearing on the internet, especially on Youtube, for example:

Cilit Bang
Cillit Bang was created by Reckitt Benckiser (who also own Gaviscon, the heartburn treatment with the famous “What a feeling advert”), and claims to remove limescale, rust, grime, and mould. It was formerly advised not to use Cillit bang with copper, despite the fact that Barry Scott clearly uses a copper penny for the penny test in the advert.

Barry Scott
Barry Scott is the fictional character, portrayed by actor Neil Burgess, who was the main cause of the advert’s internet success. Throughout the advert Scott appears to be shouting every word clearly, even when someone is standing right next to him, which many people found hilarious. Many have compared him to Billy Mays, and hailed him as his successor. He is quoted as of saying:
“Bang! And the dirt is gone!”
“Over a million women around the UK are at it!”
“Remember me? Barry Scott!”

Spread
The Cillit Bang advert was most popular in early 2006, about a year after the first Advert was aired.
