Nicole Jaffe and Gary Owens
Familiar voices of Hanna Barbera! Gary was the announcer during the final race and Nicole(Velma of Scooby Doo) was the girl in the hot rod during Herbie's test drive.
I will never have a sig line
You forgot to mention that Gary is best known as the ORIGINAL voice of Space Ghost from the 60's. (The ridiculous "Coast To Coast" nonsense doesn't exist in my world)
Have fun. Lifes' too friggin' short.
