"He's strapped in there with it!"
Guys Realize Man They Think Is Hanging On The Back Of Box Truck Is Just A Graphic

This is a video of two dudes cruising along a Tennessee highway, worried that the man they see hanging out the back of a box truck is going to fall, and hoping the driver takes the next exit to rescue him. Then they realize it’s just a giant graphic printed on the back of the truck’s door. Hey, I’ve been that high before, I get it.

Thanks to JustA, who agrees at least these guys cared and weren’t trying to get the truck to swerve or anything.
