After years of playing wholesome dad Danny Tanner on “Full House,” Bob Saget stunned some TV sitcom fans with his R-rated stand-up comedy routines.

They shouldn’t have been so surprised, he says. He was only going back to his roots.

“They should have seen me when I was 22,” he said. “I was always doing something weird and inappropriate, because (my parents) never took me to a shrink.”

But time has passed and things have changed, and Saget’s comedy has entered another phase — fitting, no doubt, for a man who recently turned 65.

“It’s funny, because I don’t feel that old in my head, but now I’m doing three minutes on Medicare,” Saget said recently from Los Angeles. “Some people are disappointed that I’m not as blue as I used to be.”

Saget will be at the Pittsburgh Improv for four shows June 25-26. Special guest will be Mike Young, a writer/comedian and creator of The Young American Comedy Tour.

Tickets are going fast. Two of the 21-and-older shows already are sold out.

The closing song for his current act, which he’s been honing in comedy clubs around the country, is called, “I Don’t Do Negative.”

“That’s my new mantra,” he said. “I do more jokes now than I used to. I talk about the human experience and what we’ve shared in the past year.

“I wouldn’t say a lot of things now that I said 25 years ago. There’s a different thoughtfulness now than there was then.”

Varied resume

What he was saying 25 years ago were adult words on adult topics like sex, drugs and death. It wasn’t anything other comedians weren’t saying, it probably just seemed shocking coming from the mouth of the beloved TV dad of the Olsen twins.

Saget was among comedians featured in the unrated 2005 film, “The Aristocrats,” with each one telling a version of what’s billed as the dirtiest joke in the world, which originated in old burlesque acts and traditionally is told only among comedians themselves.

He even brought an adult perspective to penguin mating rituals with “Farce of the Penguins,” a 2007 straight-to-video spoof based on “March of the Penguins,” the award-winning 2005 French documentary.

Saget’s motley penguin crew — voiced by the likes of Tracy Morgan, Dane Cook, Jon Lovitz, Gilbert Gottfried, Lewis Black and a number of “Full House” veterans — say things you’d expect a bunch of guys to say as they plod 70 miles to meet their mates.

Racy material aside, Saget’s resume is still long and varied.

In addition to his television and film acting credits, he’s a director and producer. He’s starred on Broadway in the Tony Award-winning play, “The Drowsy Chaperone,” and in the Tony-nominated “Hand To God.”

His stand-up special, “That’s What I’m Talkin’ About,” premiered on Showtime in 2013 and was nominated for a 2014 Grammy Award for Best Comedy Album.

He’s even a New York Times best-selling author, thanks to 2014’s “Dirty Daddy.”

In his “Here for You” podcast, he tells stories, gives advice and free-associates on topics both light and serious.

He cites edgy old-timers like Don Rickles, Rodney Dangerfield and Richard Pryor among his influences and friends. The work of Martin Mull provided inspiration for the original and parody songs in Saget’s act.

These days, he’s tight with the likes of Dave Chappelle and Bill Burr.

In recent times, Saget has been traveling around the country, working on new material as comedy clubs reopen. He says he doesn’t have any plans to slow down.

He recalled “sitting in my house with Bill Burr, 10 feet apart, smoking cigars. I told him, I haven’t even done yet what I came here to do.”

That means honing his comedy down to its purest form and continuing to make people laugh.

“I like to think I’m better than I’ve ever been,” he said. “After 45 years of doing this, I think I’m un-bombable. You gotta be confident, right?”

Especially coming out of the pandemic, he said, “I just want to do my best to make people laugh like they haven’t laughed in a long time.”

It’s been a few years since he’s been there, but Saget said he has another goal for his time in Pittsburgh: “I really need to go to Primanti’s again.”
