A new Facebook application has arrived to mark the launch of a new show on UKTV's Dave.

The app is called the Argument Killer whilst the show - Argumental - starring John Sergeant, Marcus Brigstocke and Rufus Hound - is being broadcast on Monday evenings at 9.40pm.

Both are all about witty banter with the App, which was created by digital agency Devilfish and social media agency Verbie, provides a stream of clever comebacks on any subject the user types in.

The idea is Facebookers can then memorise the putdowns and use them in arguments.

The application is available on both Facebook and on the Dave website.
