The series originally aired with a four-part "Underdog" episode running complete in its 30-minute time slot. All current TV prints are a compendium of two related shows, "The Underdog Show" and "Tennessee Tuxedo And His Tales" (but shown under the "Underdog" title), with each of their segments mixed into each 30-minute episode. Some TV prints open with a segment "introducing an exciting scene from today's 4-part episode...", but instead of going into the preview the main credits roll. The end credits use titles from both "Underdog" and "Tennessee Tuxedo" shows.
