If look closely there is a security guard that walks up with Nate.  That's a smart move on Kimmel's part, because you never know when Nate might snap and punch a dude on the street.

You also have to give props to Nate for doing it in the first place.  It can't be easy listening to dudes talk shit about how a guy you already beat is going to kick your ass.

Especially when you're a crazy person.
