Do Ben and Jessa Seewald really get along, and does the couple have what it takes to make their marriage last?

These are just some of the answers the couple debunked as they played couples' trivia with PEOPLE, revealing just how much they know about each other despite only being married for less than four months.

When PEOPLE asked who between them is more likely to wash the dishes, they both answered Jessa, but she was quick to add that "sometimes" it's Ben.

Traditional households often have the woman cooking for the family, but that is not the case for Ben and Jessa. Jessa immediately answered that Ben is the better cook, and although Ben tried to be nice by saying that he is more impressed with his wife's cooking skills, he later changed his answer.

They both answered each other when it comes to the person who has the better memory, but the decision was unanimous when it came to the person who loves fast food more. "I do love my french fries," admitted Jessa.

And apparently, Ben gabs on the phone more! "Nobody talks on the phone more than Josiah," he defended himself.

The two also agreed that Jessa would be the stricter parent. "Jessa knows how to keep the kids in line," said Ben, adding that if it were up to him, he would even let their kids sleep without brushing their teeth if they were very tired.

And speaking of children, the couple lovingly answered that they hoped their children would look like each other.

"He's the most beautiful guy in the world," said Jessa about her husband. "Your son's going to look like you and daughter's going to look like me."

The last question was, of course, a no-brainer since they were asked who has more siblings. Jessa belongs to a brood of 19 while Ben has six siblings.
