Mitt Romney, President Barack Obama

Last week's binders are this week's horses and bayonets.

President Barack Obama's sarcastic knock of Governor Mitt Romney's views on the military budget — saying the military has fewer "horses and bayonets" and Navy ships than it previously did because of changing needs — was the most tweeted-about topic of last night's third and final presidential debate.

The debate overall generated 6.5 million tweets, according to official Twitter statistics — the lowest number of all three debates. The "horses and bayonets" comment alone sparked more than 105,000 tweets and also immediately spawned a parody account, @horsesbayonette.
