After three years (and seasons) of silly shenanigans on the MTV buddy comedy reality series, “Rob & Big,” Rob Dyrdek is striking out on his own.

Although his new 12-episode series, “Rob Dyrdek’s Fantasy Factory,” revolves around the 34-year old professional skateboarder’s business interests – including clothing and toy lines and stakes in hotels and restaurants – he still manages to squeeze in plenty of wacky hijinks while working at his new 25,000 square foot Los Angeles office space dubbed the Fantasy Factory.

“I’ve lived a weird run over the last four months [while filming],” Dyrdek says, “but it’s all in the vein of chasing down ridiculousness, so it’s been a lot of fun.”

Dyrdek tells us why he’s back in action this winter.

NYP: Why didn’t you just do another season of “Rob & Big?”

RD: The thing that was killing me about “Rob & Big,” was that shooting the show was interfering with my business and skating. When it came to doing another show, I put everything under one roof – the world’s first indoor, concrete skate plaza and offices around it – so I’m able to shoot TV, skate and handle my business, all in one ball of fun.

NYP: Do we finally get to see your serious side?

RD: When it comes down to making TV, I just can’t get that serious. There’s a sense of realness with the [business] stuff that’s important to me and that I’m passionate about, but for the most part, I’m getting attacked by sharks and building foam pits and Bat Caves.

NYP: How’d you come up with the Fantasy Factory?

RD: It just evolved. Originally, I was just going to build a regular, immaculate, modern office. Then, I was like, I’m going to drive this T-Rex – a three-wheel race car – and I’m going to build a Batcave so that I can drive underneath my skate plaza. Every time I would think of something, we would just go out and do it.

NYP: Any unfulfilled fantasies?

RD: No. I did not turn down a single thing. It cost me a lot of money, I’m not going to lie. This whole operation is costing me a lot of money.

NYP: Anyone try to tell you that you were going too far?

RD: The zip line in the middle of the building, they tried to reel me in on that. They were like, “This is not safe” and I kept saying, “It is safe!” – and it’s pretty sketchy. We try to make basketball shots off it, fly off of it and land on skateboards. . .it’s getting real sketchy down there.

NYP: Do you worry about setting a bad example for kids?

RD: To a degree. You can’t help but get lost in getting stunt-y in the world that I’m in, but I don’t feel like anything that I do is what would be deemed doable to a kid. It’s impossible to do this stuff unless you have a crazy, giant warehouse and you’ve spent all the money to build this crazy stuff. And, if MTV believes that when we shoot something and it looks like a kid could copy it, they won’t let us use it.

NYP: Did MTV nix anything from the series?

RD: Nothing really this time, but in the past they did. In one episode of “Rob & Big,” I broke the Guinness World Record of doing air [on a skateboard] off the top of my house into my pool and they wouldn’t let us use that.

NYP: Will your alter-ego, R&B sensation Bobby Light, show up again?

RD: No, but Jingle-Z and Thugg D make an appearance – Jingle-Z is my favorite. Driving a car one day, I discovered I might be the Jay-Z of jingles and I don’t know it because I’ve never tried to sell a jingle to somebody. So, I recorded five jingles and sold them to Carl’s Jr. I’m going to be the greatest jingler the world has ever seen.

NYP: You’re 34. Do you plan to hang up the skateboard soon?

RD: This body is beaten like a rabid dog. Ultimately, [this period] will be sort of a transition over the next few years out of professional skateboarding, but I’ve still got a hard three [years] in me – maybe.
