Jeff finally returns from outer space. Meanwhile, Steve cares for Snot's hamster.
Tropes:
- Bowdlerize: TV schedule planners usually list the episode as "Holy ****, Jeff's Back."
- The Bus Came Back: Jeff finally returns to the Smith household.
- Came Back Wrong: It turns out that Jeff is actually an alien that has been changed to resemble him, and the real Jeff had been killed and disassembled. However, Stan likes the new Jeff more and is unhappy when they end up putting the original's brain into the alien doppelganger's body, restoring him to normal.
- Parent Never Came Back from the Store: Double Subverted. At the start of the episode, a dad is leaving his son by saying he's just going to the store for a pack of cigarettes, with the clear implication between both of them that he's actually leaving. As he reaches a crossroad, he decides to break the cycle and return home. But then a meteor hits his car, killing him.
