Marty does his parallel parking on the DeLorean time machine outside the store that Jules and Verne Brown are in. As the Comet Kahooey is about to pass the Earth's orbit, Biff declares that aliens are coming and causes the residents of Hill Valley to panic. Biff finds a "space craft" behind Doc's oleander bushes — an alien craft he recognizes from 25 years earlier and the last time comet Kahooey appeared. Biff has the military, police and assorted agencies believing that Doc is an alien. With Doc in serious trouble, Marty, Jules and Verne travel back to 1967 to straighten out the mess. Marty and the boys find that Doc has built a flying craft to view the comet and that Biff has mistaken it for an alien space ship. When Marty, Jules, and Verne appear in beekeeper suits and the DeLorean while confronting him, they make Biff promise that he won't say anything about the "visit" from the aliens — now and in the future. Biff promises and Marty, Jules and Verne head back into the future in 1992, early 1993. When they arrive, Doc is fine and Biff is trying to peddle some cheesy "alien" souvenirs without much luck.

Behind the scenes
- The episode is inconsistent with the continuity established in the films.
- When Marty, Jules, and Verne travel to 1967, they see Doc jump out of his "spaceship" and towards his mansion. However, the mansion had burned down in 1962, and Doc had then sold most of the land to developers, as shown by newspaper clippings visible in the opening moments of the film Back to the Future.
- In the film, Doc noted that it had taken his entire family fortune to build the time machine. Not only is the rebuilding of the mansion inconsistent with spending all of his spare time and money to realize the vision of time travel, so too is the construction of a spaceship capable of ascending into orbit.
- In IDW's Back to the Future comic "The Doc Who Never Was", it is established that Doc put all of his energy into inventing time travel after he sent Marty back to 1985 from 1955. In the new timeline, Doc had already invented time travel in the form of the temporal field capacitor, the predecessor of the flux capacitor, in 1962. He told the government about his time machine, and had second thoughts about it as he regretted his involvement in the Manhattan Project. He sent a letter back in time to overload the device, and purposely burned down his garage, so that he would never tell the government about his device. He was given insurance money for the garage, and mentioned that he would be able to quickly get back to where he was, as he had already done it once. Since he's ahead of schedule in inventing time travel, and knows that he'll be successful, it's possible that he's willing to spend his insurance money on something other than inventing a time machine in this timeline.
- As Marty, Jules, and Verne leave 1967, the clock on the Courthouse can be seen moving, however according to the films, after November 12, 1955, it would never move again.
- The Hill Valley Historical Society pamphlet included with Back to the Future: The Game: Deluxe Edition, stated that in 1990, in the timeline where Marty didn't hit the Rolls-Royce, the clock on the Courthouse was replaced, despite protests from the Hill Valley Historical Society. After the events of the game, Doc was allowed to pursue science by his father after they reconciled in 1931, and the Erhardt Brown Scholarship for Young Scientists was presented annually. It's possible that in this timeline, a new clock was installed some time between 1955 and 1967.
- Since Marty, Jules, and Verne arrive in 1967, 12 years after Doc helps Marty get back to 1985 in the movie trilogy, Doc should have recognized Marty.
- Doc has a history of not believing what he sees. When he saw Marty return in 1955 after he had sent him back to the future, he refused to believe that he was there, even though saw Marty with his own eyes, and even talked to him. He wouldn't listen to reason until Marty convinced him that he really was there by giving him the letter that he wrote for Marty in 1855. Since Marty never admitted who he was in 1967, Doc was able to successfully refuse to believe what his eyes were seeing.
- Marty, Jules and Verne pretend to be aliens in order to manipulate Biff, an homage to the "Darth Vader" scene in the original film.
- An earlier draft of the script for the first film called for Marty to pose as an alien to scare Biff, rather than George. And the original draft for the script to Part II, had Marty going to Hill Valley in the year 1967 in order to prevent Biff from causing problems in the present.
- "Comet Kahooey" is likely a humorous takeoff of the name of Comet Kohoutek, which approached Earth in 1973. Predictions, by some scientists, that Kohoutek would be brighter than the 1910 Halley's Comet, were spectacularly wrong.
- The time display is not shown in the episode, although Marty has chosen to go to 1967 because Biff says that he saw the alien "25 years ago". The episode was first broadcast in 1992, which was 25 years after 1967.
