K-9 Training is an episode of New Looneys starring Marvin the Martian and K-9.
Marvin is in a martian house sitting in a green recliner reading a book with K-9 at his feet.
Marvin: Look, boy! It's a picture of when I first got you! I remember that day like it was yesterday...It zooms in on the picture and then the picture becomes more and more realistic, then finally the young Marvin begins moving.
Young Marvin: Ooh, wow! A puppy dog!
Adult Marvin's voice: It was one day when I was looking around Mars. My parents wanted me to explore Mars and find things they could use to destroy earth. I found you sitting on the ground.
Young Marvin: Hi puppy dog! What's your name?
Young K-9: Woof!
Young Marvin: You don't have a name? You must be lost! I'll call you...Marvin Junior!
Young K-9 looks at Young Marvin and begins to walk away.
Young Marvin: Wait, wait! I'll call you something else! Um, um, Kay-Nyne! Or just the letter K number 9.
Young K-9: Woof!
Young K-9 begins licking Young Marvin's face.
Young Marvin: Heehee, stop that! I need to train you! Daddy says that I have to destroy Earth when I'm a grown-up, so I'll teach you how to destroy Earthlings! We can use my daddy's UFO and kidnap one!
Young Marvin and Young K-9 walk off. The image slowly turns into a picture until finally it zooms out and shows Adult Marvin showing Adult K-9.
Marvin: Of course, we never managed to kidnap an Earthling.
K-9 (under his breath): You didn't.
Marvin: What's that, K-9?
Bugs Bunny sticks his head in the window.
Bugs: Ah, what's up, doc?
Marvin looks at Bugs, then K-9 and it fades away, revealing the Warner Bros. symbol. Marvin pops out.
Marvin: That may be all for now, but beware!
