Oh my god (2004)

A man comes home from work, greeted by his dog roaming outside and by a neighbor complaining about the dog. The man bends over to pet his dog and finds that it's bleeding. "Oh my God," he mutters. He enters his house and there makes grisly discoveries, repeating over and over, "Oh my God!" and "How did this happen?" Soon his neighbor hears the exclamations. The man's fate concludes the film.
