Rocko and Arlo Have Their Dad’s Personality Traits
GettyJohnny Knoxville has spoken about how his two youngest children, Rocko and Arlo, have inherited some of his personality traits.
Per People, when Knoxville was on “The Kelly Clarkson Show” speaking to guest host Jay Leno, he revealed Rocko had inherited “the Jackass gene.”
Knoxville said, “Luckily my daughters, that gene didn’t get passed down to them. You know, girls are just smarter than boys and I don’t have to worry about them. But my son is just like my father. So he’s got this funny look in his eye so yeah, I have to worry about Rocko.”
Arlo, however, appears to have inherited Knoxville’s silliness gene. In a 2024 Instagram post, Knoxville posted two images of himself after Arlo and her friend had given him a hilarious makeover with a platinum blonde wig, lipstick, and makeup.
Knoxville said that, when they give him makeovers, “Usually they make me take them out in public afterwards.” Now that’s funny.
