Two men got into a ridiculous fight over sweet and sour sauce inside a McDonald's.  

The video was filmed in one of the fast food chain's outlets in New York's Lower East Side before being posted on Facebook, where it has been viewed five million times.

It shows two men - one in a white jacket and the other wearing a red durag on his head - squaring up to each other after trading insults. 

The video begins with the pair trash-talking each other as they gradually begin to square off, mimicking boxers as they bob side-to-side.

A couple of punches are thrown as they continually trash-talk one another.

The man wearing a durag then throws a punch at his opponent, who expertly dodges and returns with a right hand to the face.
