Jeff Fischer

Jeff Fischer is introduced as Hayley's loser, stoner, hippie boyfriend. He is an unemployed high school drop out, and is frequently naive or stupid, irritating other characters. His mother abandoned him early on, giving birth to him in his van, within which he lives ("Stan Knows Best") until Season 6. His relationship with his father Henry is poor, as his father also views him as a failure. Throughout the series, Hayley repeatedly dumps him for being needy, clingy and overly agreeable, leaving Jeff crushed until their inevitable reconciliations, though Jeff also dumps Hayley once in the episode "Pulling Double Booty". However, he marries Hayley in the show's one-hundredth episode after swindling Stan out of $50,000. He then moves into the house with Hayley in the episode "There Will Be Bad Blood". In "For Whom the Sleigh Bell Tolls", Stan ends up accepting Jeff when Jeff demonstrates his loyalty toward Hayley by saving Stan's life despite disliking him. Jeff is based on Seth MacFarlane's friend of the same name, who also voices him.
