Say, "Stop flicking semis at me."

You start to ask him to kindly cease his semi flicking, but instead you get smashed into the ground with a semi.

You claw your way through the diesel engine and out into the sweet free air only to be crushed by yet another semi.

It seems that the Hulk is grabbing them off a nearby freeway and is in the process of making the World's Largest Pile of Semis on Your Back.
