MOST OF the time, 99.9 percent or more, Scott Innes uses his power as the voice of Hanna-Barbera cartoon characters Scooby-Doo, Shaggy and Scrappy-Doo for good.

When a new cartoon movie comes out, when a video game or thrill-park ride is crafted, the Baton Rouge, La., resident is the guy who wiggles his vocal cords in a strange way to fill the soundtracks with silly dialogue or exclamations like "Zoinks!" "Ghosties!" or the immortal "Ruby-Roo!"

But every now and then, say when Innes is coming or going in the car with his 3-year-old, Presley, and some of the youngster's pals, well, that's when the versatile voice-over artist and country-music disc jockey can't help himself.

"I'll roll through the drive-in and, in the voice of Scooby-Doo or Shaggy, ask for burgers, fries and a few Scooby Snacks," said Innes, smiling at the thought. "In just about every case, what you get back is laughter. The person at the takeout window thinks it's funny."

Innes, who in his other life is an afternoon DJ for country-music radio station WYNK in Baton Rouge, was at Paramount's Kings Dominion Thursday for a special promotional opening of a new ride at the Doswell theme park.

It's called "Scooby-Doo! and the Haunted Mansion," and, inspired by the ghost-busting Scooby-Doo crew, it lets kids use little laser pistols to rack up points by shooting targets under a collection of ghosts and ghouls that pop up and out at riders.

It was unplanned cartoon kismet for the theme-park dedication to happen just the day before the second live-action film featuring the ghost-busting characters, "Scooby-Doo 2: Monsters Unleashed," opened nationally.

The 37-year-old Innes does not have a voice part in that movie, though he did the voice of Scrappy-Doo in the first film, which mixes live action and animation.

Innes joins a collection of actors who have done the voices of Scooby and crew through the years. It happened because he was such a huge fan of the cartoon when it debuted in 1969.

"Back when I was in grade school, I told my teachers that I'd be the voice of Scooby one day," said Innes.
