Ben 10: Alien Force, Season 1

Gwen Tennyson:
Those trails. They're not burned marks, they're age. The creature accelerates time!

Professor Paradox:
Very good!

Kevin Levin:
[charges for the creature] Not so fast, ugly! [punches the creature, causing his hand to get wrinkled and ages forward into an old man]

Swampfire:
[gasps] Kevin!

Gwen Tennyson:
Kevin!

Ben Tennyson:
[reverting back] Just touching that thing aged him, 60, 80 years? We've got to get him to a hospital.

Old Kevin Levin:
What are you doing? Get your hands off me.

Gwen Tennyson:
Come on Kevin, we're going to get you some help.

Old Kevin Levin :
What do you mean, "help"? I'm gonna kick that thing's keister! [his back spine pops as he kicks] Oy!

Gwen Tennyson:
Are you okay?

Old Kevin Levin:
My back is killing me, my legs ache, and what's up with these shoes? Is it too much to ask for a little support?

Gwen Tennyson:
He's like a real irritable, short-tempered, crotchety old man.

Old Kevin Levin:
Why are you whispering?

Ben Tennyson:
In other words, aside from the male-pattern baldness, he's pretty much the same as always. Come on, old man. [Old Kevin inserts his car keys into something] I'll take those. [takes the keys out of his hand]

Old Kevin Levin:
What do you think you're doing?

Ben Tennyson:
Driving.

Old Kevin Levin:
Don't even think about it, you don't have a license.

Ben Tennyson:
Grandpa Max taught me, and it's an emergency. You're nearsighted, arthritic, your reflexes are shot, and you're trying to unlock a cactus.

[Camera zooms out to reveal that Old Kevin was trying to unlock a cactus instead of his car; In Kevin's car, Ben is in the driver's seat while Old Kevin is sitting in the back]

Old Kevin Levin:
You should've gone out with me when I was young and handsome.

Gwen Tennyson:
You were too immature.

Old Kevin Levin:
What about now?

Gwen Tennyson:
Too old.

Ben Tennyson:
[backs up and accidentally bumps into some trash cans] Whoops!

Old Kevin Levin:
It's not a bumper car!
