Bob Saget and John Stamos on Full House

Bob Saget, John Stamos and Dave Coulier met on the set of their hit sitcom Full House, which ran from 1987 to 1995. Saget and Stamos played brothers-in-law, bonded in grief by the death of Pam, a.k.a. Saget's on-screen wife and Stamos' on-screen sister.

Once the series wrapped, the entire cast remained incredibly close, however it was Stamos and Saget's friendship that truly endured.

"To say we are like brothers is an understatement," Saget wrote on Stamos' birthday in 2021. "What I have to say here, is how damned lucky I am to have John in my life."

"The first four years, John and I didn't get along that well," Saget shared during a visit to PEOPLE Now with the Fuller House cast. "I was a comic, I was married, and John was a teen idol that had gone on to be a really good actor. We both learned a lot from his acting chops. He had different ladies trampsing through the —"

"Trampsing?!" interrupted Candace Cameron Bure as the rest of the cast laughed. "What is happening with this interview?

"Sorry, traipsing," Saget said. "But they were tramps."

"So the first four years of the old show we weren't as close," he added. "But then we became like brothers."
