Many Hollywood stars who knew the late Bob Saget called him "the sweetest man." One of them was the late-night show host Jimmy Kimmel, who said goodbye to the comedian on Monday's show.

Before Jimmy Kimmel Live started, Kimmel dedicated five minutes to the life of Bob Saget.

Kimmel and Saget were friends, and they regularly talked. Jimmy shared that the late actor sometimes messaged him "just to tell me he loved me."

In a heartfelt monologue, the host stated:

"When you walked into a party, you saw Bob and his wife Kelly in the corner, you go straight to them and stay for as long as you could because he had something funny to say about everything and nothing bad to say about anyone, never."

"There were people he didn't like, he kept it to himself. Unlike me, he was a good person."

While preparing for this tribute, Kimmel said he went through their old emails and revealed that Bob was "very serious about life and the well-being of our children."

He shared a personal experience:

"When my son was in the hospital, Bob checked in a lot, so I want to send love to his daughters, to his wife Kelly, and to his friends who loved him so much."

The host shared a clip from 2017 featuring Saget and his Full House co-star and friend, John Stamos. They gathered to honor Don Rickles.

Tearful Kimmer further added:

"We never imagined that four and a half years later we'd be talking about [Saget's death]."

"I'm sorry, I taped this like 14 times, and I just, anyway, we had a beautiful conversation that night. You could see when John and Bob were talking about how much they loved Don, how much they love each other, so I thought it might be nice before we go on with the regular show to share just a bit of that one more time as we remember Bob."

Kimmel is one of many famous people who was a true fan of Segel as an actor and person.
