Let's say you have a boat...
And the boat hitch with the boat on it comes loose from your car...
a) Watch it go, waving goodbye and praying it doesn't hit anything?
b) Jump in front of it and try to stop it from rolling down the street?
c) Hold onto the hitch, and hope you turn into the Incredible Hulk so you can stop it with your strength?
Well, this David Banner decided to try 'c', and wait to turn green.
Unfortunately he never did.
