A Mcdonald's employee tested out the new 'McKnockout Sandwich' on a customer who was trying to cause trouble.

The incident happened on the Michigan State campus, and witnesses said that the customer was definitely instigating the situation.

Kevin Lange is the MSU student who filmed the entire thing, and said that the customer had spit on the counter, and appeared to be pretty drunk.

The only thing that would have made this better is if the McDonald's employee would've asked him if he wanted fries with that, after he knocked him out.
