"Doughnuts. Is there anything they can't do" OK, that isn't one of the famous Homer Simpson quotes drivers will now find on the TomTom GPS app for the iPhone. But with Homer as a co-pilot, drivers need to get in the spirit of Homer-isms: "Make a U-turn. Ha ha, you've goofed. D'oh!"

TomTom today announced that the voice of Homer Simpson, (Dan Castellaneta) of the long-running TV series "The Simpsons," can be downloaded for $5.99. The Homer Simpson voice requires version 1.7 of the TomTom App (available for $49.99) installed.

"Homer's skills will help keep drivers and fans entertained in a light-hearted and familiar way. It's exciting to have him onboard!" said Alain Pakiry, senior vice president of marketing at TomTom.

The Homer Simpson voice for the TomTom App is available in the U.S., as well as Australia, Belgium, Canada, Denmark, Finland, Ireland, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, South Africa, and Sweden. And, of course, Springfield.
