Jerry Fields is the number one dentist in the Langley Falls - Chimdale - Lanceton triangle, and the husband of Meredith Fields.
When Roger, who has come to feel like he is nobody without his invented personas in "The Dentist's Wife", is inspired by Meredith to be anyone he wants, he chooses to be Meredith herself since she is real. He manages to take over her life, sending her off on a barge and even fools Jerry. Francine's attempt to talk some sense into him results in him sending her off on a barge as well. They meet up on the barge at set off to stop Roger at a charity gala, where he is introduced by Jerry prior to their arrival.
Jerry is voiced by Billy Van Zandt.
