"A wallpaper of one of the funniest characters from The Simpsons."
One character better defined than the hundreds that populate the universe of The Simpsons is definitely Police Chief Clancy Wiggum. He's one of the funniest, most charismatic and friendly of the whole series, and is characterized especially for inefficiency and incompetence.
And to him is dedicated this wallpaper, shown in a pose usual for him, ie trying to think, confused, dazed and hesitant in his chair at the station, probably thinking more about eating donuts than resolving any case.
This wallpaper of the clueless Wiggum is only available in a size of 1024x768 pixels.
