None of his colleagues will join him for a drink and a cake in his honor has an iced portion of the phrase '' Good riddance , asshole '' sliced out .

The crash damages the fence of local Judge Evans , who sentences him to community service at a nearby hospital . Ben offers to pay for the fence , but the stern judge increases his community service each time he talks back . Defeated , he reports to the hospital , where Nurse Packer humbles him by ordering him to clock in and out , as would a factory worker . Though upset , Ben quickly makes friends with Mayor Nick Nicholson , the town cafe's proprietor/head waitress , and Melvin , the local mechanic tasked with repairing Ben's car . Ben soon finds his clinic work to be much more laid-back than the emergency room . He has simple cases such as spots before the eyes , fishing hook impalings , and even reading mail for a young illiterate couple , whose baby he later delivers .

Imagine a glass of your favorite drink that never became empty. Now think about what really happens. You take a drink and there is less in the glass. You keep drinking and soon it is all gone.

Its too bad that many things here on Earth will run out. This includes some of our natural resources we depend on. Things like oil will not last forever. There is a limited supply.
