Me and my buddy found this little trick by mistake last night. Its nothing ground breaking but its a fun little thing. As you can see in the first picture I attached you simply activate the box right where I'm sitting and it begins the quest dialogue. Soon as they are finished talking you've completed the quest.
Edit: Heres the images on a site
