A group of aliens worship Jenny after she is mistaken for a “comet goddess”. It's fun at first but they soon drive Jenny crazy. However, when the aliens demand that Jenny summon the sun to turn her Earth into a comet, she retaliates by putting their spaceship in orbit around the sun. The Earth is saved, but someone's missing… / Turns out, poor Sheldon was stuck on the aliens' ship when Jenny got rid of it, and he's been spending decades trying to get back to Earth (even though it's only been about 24 hours on Earth since he left). Hopefully, Jenny can get him back to his proper age.
