My Life as a Teenage Robot, Season 3

Old Sheldon:
Jenny! [slowly walks towards Jenny and hits her on the head with his cane] You ruined my life! [falls on his back]

Jenny:
Who are you, and what are you talking about?

Old Sheldon:
[sits up] I'm your old pal! Sheldon!

Tuck:
Crazy old person.

Brad:
Move away slowly.

Old Sheldon:
I'm Sheldon I tell ya! I just got me a few wrinkles since you abandoned me… [falls on his back again] 75 years ago!

Brad:
That's crazy talk, pops.

Jenny:
We just saw Sheldon yesterday.

Tuck:
Yeah, hangin' out with those freaky Jenny worshiping aliens.

Old Sheldon:
Those awful aliens. I remember it like it was yesterday.

Tuck:
It was yesterday, you old--

Old Sheldon:
[covers Tuck's mouth with his hand from talking] Hush, boy! I'm telling a story. When Jenny hurled those aliens into outer space… [Flashback to the previous episode; voice-over] I was onboard. I tried to get 'em to turn around, but there was a bit of a communication gap. Catching a ride back was impossible! I had to find work to survive. I couldn't keep up as a mechanic, couldn't master beauty salon work, and couldn't stomach the fast food industry.
