Patrick Warburton, best known for playing the hilariously deadpan David Puddy on “Seinfeld” and voicing Joe Swanson on “Family Guy,” says not everyone was a fan of his success, particularly his “very religious” parents, who disapproved of his roles and called some of his work “blasphemy.”

In a candid interview with Fox News Digital, the actor opened up about the tension between his career and his parents’ devout Catholic beliefs.

“They don’t see it as satire. They see it as blasphemy,” Warburton said of his parents’ views on “Family Guy,” the long-running animated series he’s worked on since 1999. “So, it was just a conversation that we were never really able to have. We never saw eye to eye on it. But, yeah, they always hated that show.”

His father, John Warburton, once studied at the Abbey of Our Lady of Gethsemani in Kentucky, where famed Catholic monk Thomas Merton was his spiritual advisor. Though John ultimately pursued a career in medicine, faith remained central in his life. Warburton noted, “He was one of the most famous Catholic scholars of our day.”

His mother, Barbara, was even more committed to her religious convictions. “If Mom could possibly be worse than Dad, she is, yes,” Warburton joked. “My mother belonged to the American Television Council, and they were trying to get the show canceled.”

He recalled a particularly ironic moment: “I was helping support my parents with “Family Guy” money. She tried to get me to sign the petition [to cancel the show]. I said, ‘Mom, if you don’t think I’m going to talk about this publicly, this is the greatest irony. You’re laundering money. You’re laundering it to yourself.’ They hate it more today.”

Even his breakout role on “Seinfeld” didn’t escape his parents’ moral scrutiny. Warburton’s character, Puddy, debuted in the 1995 episode “The Fusilli Jerry,” which featured a storyline involving a shared romantic move. The response from his father was intense. “I received a six-page letter from my father about how disappointed he was and the choices I was making,” he said. “So, they had an issue with not dealing with the sex act with any sanctity… It’s all about procreating and nothing else.”

Warburton shared another story that illustrated his mother’s passionate mission to convert others to Catholicism, including his coworkers. “My mom says, ‘Are you going to work on “Seinfeld” today?’ I said, ‘I am, as a matter of fact.’ And she said, ‘I have this dynamic videotape that has converted a lot of my Jewish friends. If I gave it to you, would you give it to Jerry [Seinfeld]?’”

He added, “Dad actually piped in and said, ‘Barbara, leave well enough alone.’ So, at least he still had that common sense about him.”

Years later, his mother doubled down during one of Jerry Seinfeld’s stand-up shows. “She goes, ‘He was wonderful. I even wrote him a lovely thank-you letter.’ That’s when the hair on the back of my neck stood up… ‘You probably left a DVD.’ And she goes, ‘I did.’”

Warburton laughed, recalling the moment he later brought it up to Seinfeld in New York. “We had a laugh, but yeah, I’m sure he didn’t watch it. He hasn’t converted yet, as far as I know.”

Though he’s previously called himself a “bad Catholic,” Warburton admitted that faith still shapes his conscience. “Catholic guilt runs deep,” he said. “But I believe that God has a sense of humor.”
