While promoting his new memoir “Promised Land” on “Jimmy Kimmel Live” on Thursday night, former President Barack Obama revealed the humorous reason he’s “scared” of both his wife Michelle and his youngest daughter Sasha.

“Sasha is a mini Michelle,” Obama said. “I’m afraid of Michelle and Sasha, having seen that, basically has the same look and same attitude.”

He went on to explain that while Sasha takes after the former First Lady, “Malia is more like me temperamentally.”

“We call ourselves ‘The Long Faces,’ because [Malia’s] face is more shaped like mine, and ‘The Round Faces’ are Michelle and Sasha,” Obama said. “The Round Faces are a fiercer tribe. We’re like the vegetarians, the gatherers, and they’re the hunters. We try to keep the peace with them… I’m generally the brunt of jokes in my house.”

In the actual memoir, Obama opened up about the challenges of becoming a father.

“My dad wasn’t there when I was growing up. When I married Michelle and we talked about starting a family, I said to myself, ‘I’m going to do things differently. I’m going to make sure my daughters know me, they know they’re loved, they know they’re supported,'” he told Kimmel. “Overall, they say, I think, I did a good job on that front, but there were a lot of times that I’d be gone more than I wanted, especially during the campaign for the presidency. There were times where I’d have to leave early, in the middle of something, because some crisis comes up.”

“Maybe most frustrating, I couldn’t do normal stuff with them,” Obama continued. “If we wanted to go to a bookstore while I was president, you’d have the SWAT teams, they’d have to bolt down the manhole covers in front of the store.”

Regardless of how busy he was while in office, Obama made sure to have dinner with his family every night, something that he believes helped his performance in the White House.

“The good news was — and I didn’t anticipate this, but it ended up being a weird benefit of the presidency — you don’t have a commute because you live above the store. I was able to make sure I was having dinner with them every night at 6:30,” he said. “You come down from the situation room and suddenly you’re hearing about some dorky boy at school or witnessing an argument between Michelle and Sasha about whether Sasha’s going to actually eat that spinach or not.”
