Philadelphia native and "Dirty Daddy" Bob Saget brings his R-rated brand of comedy to the Sands Bethlehem Event Center 8 p.m. April 19.

Saget doesn't consider himself a touring standup comedian in the traditional sense. His live shows are grouped into small blocks of dates in nearby cities rather than months of performances across the country.

"It's actually not much of a tour. That's what I like about it," Saget says in a phone interview.

"My agent planned these gigs where I am coming to New York and to Philly [for two shows] and then to Bethlehem," Saget explains."That is on tour because it is four dates of consequence in a row and I like it. It's funny. I guess I'm a spoiled guy on tour."

Comparing himself to his peers in the comedy world, Saget is in awe of some of their rigorous performance calendars.

"I look at Jim Gaffigan and I just go, 'You amazing creature.' And I have a bunch of friends that do that. They're just out every day. And you know, you look at Louis C.K., how he tours, and my friend Bill Burr, who is just astonishing. Every day they'll just do a different venue. I'm not made that way."

Saget, a performer who readily steps up to the mic for a good cause, recently headlined a charity comedy show at the popular South by Southwest festival, Austin, Tex., benefitting the Ally Coalition, which supports LGBT and questioning youth.

Closest to his heart without a doubt would be the work he does on behalf of the Scleroderma Research Foundation, of which he is a board member. Saget's sister, a Philadelphia teacher, Gay Saget, died from the autoimmune disorder in 1994 at age 47.

"We have a benefit in LA June 5th and so far I've got Jimmy Kimmel doing the auction with me, and Jeff Garlin doing a set and Bill Burr doing a set," he says. "It's a comedy event: Cool Comedy, Hot Cuisine. I'm proud of it. It's just a gift. Comedians are unusual people if they can do something they'll do it."

Saget last performed at the Sands Bethlehem Event Center in 2012 and since then he has had a successful comedy special, "That's What I Am Talkin' About" and authored the memoir, "Dirty Daddy."

"The book became a New York Times bestseller. I don't know who they paid off but I was very happy," he quips.

Describing the material he's doing in his show, he says, "I started to write some new songs and a lot of different material that's a little more like stories because I do a lot of stuff that's always been a bunch of one-liners and then weave it around a story and then I get a little esoteric. I'm like a nine-year-old that learned dirty words. Bathroom comedy, of course, hits the fan. It's just really fun for me."

Following this month's dates, Saget is leaving his schedule fairly open to begin directing work on an independent feature he is involved with. Saget was hesitant to spill too many details but did toss out a few morsels:

"I don't want to plug it before it hits the world but it's a family comedy that represents how messed up families can be. We've seen a lot of those kind of movies and this one is particularly interesting because there's a 15-year-old boy at the center of it that you feel has some serious problems so the family tries to help him.

"It's an observational comedy of what happens when 10 people are in a house trying to help somebody. It was written by Joshua Turek, who I've been attached to for three years with this project."

The actors for the lead roles have been pre-cast but pre-production has yet to commence. "I've been asked to keep it on the DL [Down Low]. It's kind of bad luck and silly to talk about something on my part if it's not like, 'Oh we're shooting in July.' If it changes tomorrow, I'll call you," he laughs.

There are other projects in the works for Saget, including a game show type pilot and a half-hour comedy series. Those concepts are now being shopped around to networks and executives.

"I'm in development on another project which I won't tell you about but that's another one which is more of an acting role. I'm always juggling."

Most associate Saget with the TV sitcom "Full House" (1987-1995). The family comedy starring Saget is still fondly recalled by many Gen Xers and Millennials who grew up watching the escapades of the extended Tanner family.

Asked about the possibility of a reunion now that 20 years has passed since the show aired, Saget says, "There's talk of something that's really more about the kids, which I'm thrilled for because I'd like to see Candice, Jodie and Andréa do something. So, I'll see what fruition that comes to and then you just wonder if you're going to make a cameo in something like that."

"I'm not one of those guys that go, 'Leave me alone.' I went through that phase of the great genius Leonard Nimoy, 'I am not Spock,' and then his next book was 'I am Spock.'"

"I am Birdman," he laughs, referencing the Academy award-winning Michael Keaton film.

"You know, I'll walk to the street, not in my underwear, and people will say, 'Weren't you?' 'Yes' 'Would you take a picture?' 'Sure' and then I try and go off and do the new thing that reinvents me as an artist."
