Cool dad alert! George Clooney opened up about fatherhood in a new interview, and revealed that he is having a sense of humor about raising daughter Ella and son Alexander, his four-month-old twins with wife Amal Clooney.

Chatting with People at the Suburbicon premiere in LA on Sunday, Oct. 22, the handsome new dad, 56, said that he hopes to teach his kids the art of pulling the perfect prank. “When you’re directing, you’re busy. When you’re acting, you’ve got a lot of time and you can do all kinds of horrible things,” George — who is notorious for pranking his co-stars on set — told the publication. “I’m already trying to teach my children dirty tricks.”

George went on to describe the go-to trick that he can’t wait to practice with his little ones. “Like the peanut butter on the tennis shoe move. You walk into a party with peanut butter on your tennis shoe, and you look around and you ask anybody if it smells like crap,” the ER alum said. “And then you reach down and you actually taste the peanut butter off your shoe with your finger. That will really throw people up. That’s a rough one.”

Kidding aside, the Oscar winner previously revealed how the experience of first-time parenthood has affected him and his 39-year-old spouse while speaking with the Associated Press back in August. “Suddenly, you’re responsible for other people, which is terrifying,” he admitted. “[Amal is] like an Olympic athlete. She’s doing so beautifully.”

George, who tied the knot with Amal in September 2014, also said that he doesn’t let the gorgeous lawyer and human rights activist do all the grunt work alone. “Right now, my job is changing diapers and walking them around a little bit,” he said at the time. “I really didn’t think at 56, that I would be the parent of twins. Don’t make plans. You always have to just enjoy the ride.”
