Plot (Spoiler)
After hearing Quagmire brag about his sexual exploits, Peter feels that he has missed out on enjoying the single lifestyle. Death is summoned to The Drunken Clam on a false alarm, and he grants Peter’s wish by sending him (along with Brian) back to 1984 for one night. Appearing to others as his 18-year-old self, Peter cancels his scheduled movie date to see Zapped! with Lois Pewterschmidt, instead accepting an invitation from Cleveland to go and party at a bar. Peter enjoys the evening, and ends up making out with actress Molly Ringwald, when Death appears to return him to the present. Back in the present day, Peter then discovers that his past actions have had drastic effects on the world; he and Molly have been married for 20 years, Lois is married to Quagmire, Al Gore is president instead of former U.S. President George W. Bush, Chris, Meg, and Stewie have Quagmire’s chin, nose, and mannerisms, Dick Cheney, who is just known as the chairman of Halliburton, has just shot dead Antonin Scalia, Karl Rove, and Tucker Carlson, and finally, Chevy Chase is the host of The Tonight Show. Brian explains to Peter that by missing out on his date with Lois and making out with Molly, he altered the time line. At the end of the episode, Peter says “I’m just glad everything is back to normal” and then Roger the Alien from American Dad!walks in and says “Who ate all the pecan sandies?”
