Phil Proctor (another name that appears in the "Additional Voices" section of pretty much every animated film made in the USA; the one regular role I can think of is Howard (Phil & Lil's father) on "Rugrats")
Oh sheesh. But really he's most famous as one of the members of the Firesign Theatre. (All of the members of the Firesign Theatre were in an episode of the animated "The Tick" doing voices of henchmen of an evil dolphin voiced by Maurice LaMarche.)
