Mr. Yuk, the poster child for poisoning prevention, debuted in 1971. On the occasion of his 50th birthday, we caught up with Mr. Yuk’s creator, Dr. Richard Moriarty (MD ’66), a Pitt School of Medicine alumnus and longtime associate professor of pediatrics. This episode was based on a 2003 Pitt Med magazine story, “It’s Not Easy Being Green,” written by Sally Ann Flecker, and adapted and produced by Elaine Vitone. Our executive producer is Erica Lloyd. Music by Blue Dot Sessions. Pitt Med magazine is published by the University of Pittsburgh Office of University Communications and Marketing and the School of Medicine.
