Brad Paisley Teaches His Son Some ‘Office’ Humor, Likens His House to Comic-Con

Brad Paisley is a funny guy. So, naturally, it was only a matter of time before his two young sons -- 4-year-old Huck and 2-year-old Jasper -- started to mirror dad's unique sense of humor.

"I taught my son to say, 'That's what she said,'" Paisley, clearly a fan of 'The Office,' tells PEOPLE. "He'll use it for any and all situations. It brings the house down! [My wife] thinks it's both hilarious and horrifying."

Paisley and his sons keep the house entertained, especially with Dad's passion for 'Star Trek.' "I'm one of the few 'Star Trek' fans with children, who've actually had the ability to accomplish what you have to accomplish to have a child," Paisley says. "I love 'Star Trek,' I love 'Battlestar Galactica,' I love 'Star Wars,' and my kids are into superheroes ... it's like Comic-Con at our house."

Paisley will need to take a brief break from the superhero activities at home starting in May, when he launches his H2O II Tour. Click here for a complete list of dates where the tour will be stopping.
