Comic-Con 2014: The improv team behind TruTV's popular hidden camera comedy series also tell TheWrap about their new show, national tour and zombie killing plans

Tru TV's “Impractical Jokers,” now in its fourth season, has helped create an environment of humor and fear for those who unwittingly come across the comedy troupe of Sal Vulcano, Brian Quinn, James Murray and Joe Gatto. But when they joined Greg Gilman at TheWrap's Comic-Con video lounge at the “Walking Dead Escape” in Petco Park, the joke — and the fear — was on them.

Eyeing Gilman's expertly applied zombie make-up, Vulcano said tentatively, “I feel like there's a real medical emergency going on here — I keep looking at it and thinking, ‘How are you asking us questions?’ Like…”

“Like you should get that checked,” Gatto helpfully added.

But it wasn't long before they allowed themselves to be steered back to discussing their show, which just got picked up for a fourth season this spring in addition to a six-episode spin-off, “Jokers Wild.”

“We're basically TV gods,” Quinn joked. “‘Jokers Wild’ is a sketch comedy show. Like you said, we were an improv group called The Tenderloins, and sketch comedy was our background. So after doing ‘Impractical Jokers,’ Tru [TV] was like, ‘Hey you want another show, too?’ And we were like, ‘Yeah, let's do sketch comedy.’ So it's back to what we do best.”

Which isn't to say they've given up on their hidden camera agenda — especially not when they've created classic moments like pretending to be the opening band for an Imagine Dragons show, during which Gatto and Vulcano took to the stage in front of tens of thousands of fans and not only botched playing their instruments, they continually said the band's name wrong. In fact, the crew will be employing hidden camera tricks on their upcoming national tour. That is, if they survive the zombie walk at Petco Park.

“He was going to do the zombie run in a moment and actually kill people,” Vulcano said.

“Yeah, I was actually going to put down zombies and be like, what? I got into it,” Gatto said. “I mean, as long as you do it in a funny way…”
