Jon Heder, Napoleon Dynamite star, and his wife Kirsten welcomed Evan Jane into the world last month.

Jon, 29, was interviewed by People at the Surf's Up premiere on Saturday. The first question they asked was if fatherhood brought any surprises. He replied, "I think I was basically prepared for everything."

"I didn't realize changing diapers was going to be as fun. That was actually the thing I was most apprehensive about, but now it's like, 'Let's change a diaper! I hope she's made a doodoo, so I can just change it.' " Only Jon would like to change dirty diapers! But apparently, Evan Jane enjoys her diaper changes as much as Dad: "She's always awake and happy and playful when she gets a diaper change," Heder said.
