Notes
“The Racing Mule”: Technical issues during the debut of U-Pick Live caused this episode to not actually premiere as it was supposed to on October 14, 2002. A repeat of the full episode was scheduled over a year later on November 19, 2003 at 6:30pm (also during the U-Pick Live block), but it again had the same issues for part of the episode (the episode “Married” airing instead). The date listed above (January 11, 2004) was the first time the episode aired in full with no issues.
