Mater's Lube Job

This is a scene from a fanfic I'm writing, which for some strange reason I am unable to post on this site. Oh, well. Guess I'll try again later. If you're curious you can find it on Fanfiction.net under the title "I'll Meet You On Route 62." My pen name is Twilit Violet. It's in the Movies section under Cars.
 
This particular scene is from chapter one. Mater is in the middle of getting a lube job from Doc when a tractor stampede draws Doc's attention outside. Mater tries to get down off the lift to go see what's happening, and has some trouble. When Doc comes back, he finds Mater like this.
