While working as a cameraman for KPHO, Kwiatkowski became involved with the "It's Wallace?" program, hosted by Bill Thompson (Wallace). He developed his Ladmo character there, as well as his trademark "Ladmo Bags," which were given out as prizes on the show. Kwiatkowski and Thompson thus began a professional partnership that lasted decades—with "It's Wallace?" eventually being renamed "The Wallace and Ladmo Show". Its final taping was on December 29, 1989, after a 36-year run, becoming one of the longest-running daily children's television shows in American broadcasting. By that time the show had won many awards, including nine Emmy awards.
