"El Viaje Misterioso de Nuestro Jomer (The Mysterious Voyage of Homer)" (a.k.a. "The Mysterious Voyage of Our Homer") is the ninth episode of Season 8. A more accurate translation of the episode title from Spanish is "The Mysterious Trip of Our 'Jomer'." Nuestro is Spanish for "our," and "Jomer" is a Spanish pronunciation wordplay on "Homer" (in Spanish, the letter J is pronounced as an English H). Johnny Cash guest stars.
