Pat Sajak had big news for Wheel of Fortune fans this week.

The longtime host, 74, shared a rare family update at the end of Wheel of Fortune on Monday. He surprised Vanna White and fans with what he jokingly called "a little parental bragging."

Pat Sajak's family news on Wheel of Fortune episode

As Wheel of Fortune was wrapping up, proud father Pat Sajak told his co-host Vanna White: "So you know my son Patrick, you've known him all his life.

"Well he's made it through medical school, and he is now officially Dr. Sajak, and we are very thrilled about that," Sajak announced.

Along with the news, the Wheel of Fortune host had a few laughs about his son's big accomplishment. He joked that he and his wife "tried to get [their son] into geriatrics but he refused."

He added, "The only troubling part is that he insists that I call him Dr. Sajak," which the audience enjoyed.
