Trivia

 * The real siblings of Abe are Hubert Simpson, Tyrone Simpson, Cyrus Simpson, Hortense Simpson, Bill Simpson and Chet Simpson, as Abraham's whole story about Christmas is obviously one of his false stories.
 * He looks like Luke Perry, Krusty the Clown's half-brother. Oddly enough, their names are also similar.
