The Cartoon Quote Game...

That'd be Inspector Fenwick, issuing a directive to the Idiot Hero, Dudley Do-Right Of The Mounties, as produced by Jay Ward Productions.

Ooh, applause for picking a Gerard Baldwin work; that's a nice homage and impeccable timing.

"Okay, on my signal, cut left."
[gives signal]
"Your other left."

Can't find it anywhere. It's not even on Google.

Oh dear, I'd better give a nice hint: this comes from an animation studio that's still extant, trying to mimic the success of another housepets-turned-heroes series.

Oh dear, no love for the Biker Mice From Mars, a Marvel Production trying to ride the coattails of Teenage Mutant Ninja Turtles. The quote comes from the premiere episode, while Throttle and Vinnie attempt to entwine the legs of Limburger's mobile gun platform.

Sorry if I never saw that show. I just didn't get into it.

Ah, then I'll try to stick to animated features, which have a much wider circulation.

"Well, come on, boy. Let's go home."

Didn't take very long to find this one. It's Amos Slade, talking to Copper, from "The Fox And The Hound."

Yes, this is the climactic line of antagonist Amos Slade from Disney's The Fox And The Hound, who took himself and bloodhound Copper to the game preserve to slay the fox Tod. However, after Tod deflects an angry bear away from Slade and Copper, Amos gets a moment to rethink his motives, and concludes that a petty vengeance would be mighty low thing to do.

Thanks, OUB. Now to venture once again into untapped regions:

"They say that the story of the west was written from the saddle of a horse. But it's never been told from the heart of one."

Verily, I know this one, but I'll shut up to let the nice players have a crack at it.

Found it. It's Spirit, from Spirit: Stallion of the Cimarron.

You placed your bet on the right horse, Salty. It certainly is Spirit. Good job. . Next quote's all yours.

"My leg, what was that!"
"A spaceship."
"Spaceship? Earth finally made it, eh? Off the ground at last."

Hint: This quote is from a 1965 Belgian-American animated film.

Well, I have the film, but not the one who said it. Besides, I'm leaving town again due to a death in the family, so it's best to let someone else answer.

Sorry to hear that, my condolences.

Hint 2: The quote is in the very beginning of the film. You can also find it on YouTube easily.

I have it now. It's the Blue Fairy and her mom from "Pinocchio In Outer Space."
