David Feherty opens season 3 of Feherty (Golf Channel, Monday, 10 p.m.) tackling a fairly big subject: Jack Nicklaus.

Nicklaus presented a challenge for Feherty. Golf’s most unconventional personality didn’t want to do a conventional interview with the greatest player ever.

“People might ask:  Why did you wait until the third season before interviewing the greatest golfer of all time?” Feherty said. “Well, I think I wanted to climb a few smaller hills before I tackled Everest, because what do you ask Jack Nicklaus that he has not been asked a thousand times before.”

Feherty thinks he accomplished his mission. He said “people will a different side of (Nicklaus).”

“Jack’s funny,” Feherty said. “People don’t think of Jack Nicklaus as being funny, and he’s a grumpy old man in a lot of ways.  But he has a wealth of knowledge ‑‑ between him and Barbara, their sense of family and the grandchildren and everything that sort of comes with the Nicklaus name has a really high quality, how you would like your own to be.  And it’s the humor, behind the scenes at the Memorial or in the commercial for CBS ‑‑ wearing my CBS hat; he loves it.  He loves giving people a hard time, and refusing to play with record (audio interference) or taking the piss out of people, that kind of thing.”
