If you've never considered the differences between the left side and the right side of a Twix chocolate bar, the Twix 'Ideologies' campaign will set you straight.

Created by BBDO New York, the campaign includes a TV spot about two brothers living in the Victorian age who invented one long Twix bar. However, at their presentation, they accidentally break the long Twix bar into two pieces, creating the left and right sides of Twix. The quirky commercial goes on to show how this begins their feuding, leading each of the brothers to create a Twix factory -- one for the left side of the bar and one for the right side of the bar.

The Twix 'Ideologies' ad is also accompanied by faux ads on the Twix's Facebook page, which showcase the attributes of each side of a Twix bar and the "differences" in how they are made.
