The Terminator Model 33 1/3 is sent back in time to the year 1967, in a vain attempt to change the future, and stop the giant child who will grow up to mock it, by photoshopping it into funny pictures. Here it's image was captured as it tries to run down the helpless child with a semi truck at night.
Why the giant child was crawling in the street is unclear. When asked, his parents said "You try to stop him", "He's Huge!".
