The syndicated series, as shown in the United States, is a potpourri of segments from previously aired versions of the show. Prior to a 1994 remaster, each episode included a "teaser" at the top of the show, asking viewers to stay tuned for a clip from "today's four-part story." (This originates from a 1969–1973 NBC Saturday morning rerun version of the show.) However, never more than two parts of the "Underdog" stories were ever shown in any half-hour program. Prints of such would either be followed by a closing and credits or no credits at all. The closing (which showed the first portion of a variation of the "Underdog" theme showing a giant terrorizing the city with George S. Irving, the series narrator, saying, "Looks like this is the end! But don't miss our next Underdog Show!" in place of the theme music) followed by the end credits (re-edited from the cast credits for "Underdog" and "Tennessee Tuxedo"), originated from a 1965 repackaged syndicated series, "Cartoon Cut-Ups," which originally featured Underdog, Tennessee Tuxedo, and Commander McBragg.
