Crazy Siting on 495

I saw the weirdest thing when I was driving home from the gym. There was a Uhaul truck with the back door open driving two lanes over.  You could see 2 couches stored back there. If that wasn't bad enough, I noticed legs and feet moving.  I then realized that there were people sitting on the couches as the truck was driving down the highway.  What the heck?!  I was secretly hoping that a cop was driving nearby to pull them over for being so dangerous and stupid!
