Vince Vaughn says parenthood means having someone who is forced to listen to him.

The Internship actor - whose pregnant wife, realtor Kyla Weber, gave birth to the couple's first child, daughter Locklyn, in December 2010 - joked the best thing about being a dad is that Locklyn must pay attention to everything he says.

"It gives me someone that I can sit down [with] who really needs to listen to me. All kids bring their own joy, it's a lot of fun. There's nothing more fun than laughing and playing around with the kids," he said.

Vince, 43, reunited with his Wedding Crashers co-star Owen Wilson, 44 - who has a two-year-old son Ford, with ex-girlfriend Jade Duell - for The Internship and the proud fathers couldn't resists comparing notes about their kids on set. "Our kids are literally about the same age, so it was fun for us to swap pictures and stories," Vince explained.
