My Life as a Teenage Robot - Good Old Sheldon

Seizoen: 3 - Aflevering: 2 / 52 - Eerst uitgezonden: 05 oktober 2008 - Episode ID: 521558

Turns out, poor Sheldon was stuck on the aliens' ship when Jenny got rid of it (in the previous episode), and he's been spending decades trying to get back to Earth (even though it's only been a short time on Earth since he left). Hopefully, Jenny can get him back to his proper age.
