The hosts are graduates of Baylor University in Waco, TX.
Chip and Joanna have four kids together, Drake (age 12), Ella Rose (age 11), Duke (age 9), and Emmie Kay (age 7) with their fifth child on the way in 2018.
One kid looks like Chip, while the other 3 look like Joanna. They call him "Chip Kid" to identify him.
Chip is a brother of the Kappa Sigma fraternity.
Johanna's father actually owned a tire store, where Chip was a regular customer, and Chip fancied her so much that he would not buy a whole set of tires all at once, and would deliberately pretend there was something wrong with the car, in order to see Joanna more, finally striking up the courage to ask her out on a date, but she turned him down at first, and finally relented, because he was quite insistent.
