Dave Shutton is a journalist who works for The Springfield Shopper. He wears a fedora similar to those worn by reporters of the 1940s.
His main appearance was in the Season 2 episode Two Cars in Every Garage and Three Eyes on Every Fish, where he was the reporter who helped Bart and Lisa expose the story of the Nuclear Power Plant poisoning the water and creating Blinky, the three-eyed fish. In the Season 3 episode Radio Bart, he was the reporter who first heard "Timmy O'Toole" in the well.
Kent Brockman seems to hold him in slight contempt, possibly because they work in different news mediums. When Shutton arrived at a scene and asked what was going on, Brockman replied, "Oh, do your research, Shutton!"
Dave is also seen among the media hounds who ask questions about King Homer and take his pictures, which enrages the giant gorilla. When King Homer breaks free from his restraints and gets loose in the theatre, all the journalists and photographers flee for their lives, except for Dave, who screams in terror before being squashed dead when King Homer steps on him.
In his most recent, eminent role, Dave comes across Santa's Little Helper in the Simpsons' backyard. He finds the dog balancing a beer can on his nose and Dave, finding this action to be noteworthy, takes a pic of him, saying "A shot like this only comes once in a lifetime." The last four words he repeats after the can begins to fall of dog's nose and the photojournalist places the can back on it. The shot is subsequently featured on the front page of the Springfield Shopper, which would grab the attention of Duff Beer.
Note: Many of his appearances are brief, background roles. Episodes in which he has an actual role are in bold.
