"Did you really have sex with a girl on Nanny's recliner and break it because you 'hit it' too hard?" Chase asks as his first question.

"Yes," Chrisley truthfully answers.

"Is Savannah your favorite child?" Savannah, Todd's next interrogator, asks.

"No," Chrisley again answers truthfully.

"He told the truth? That's heartbreaking," she whispers to the lie detector specialist before changing her line of questioning. "Have you ever had an STD?"

"No," Chrisley laughs, this time it's clearly a lie.

"I got crabs when I was 16 years old from the football coach's daughter and I had to go to the Revco nine miles away so the pharmacist would not know us," Chrisley explains to the camera in a confessional with his wife, Julie.

"That's sick!" she replies.

"Well you know that. You were the second one that gave it to me," he jokes.

ET caught up with Todd in 2014, where he dished all about raising his rambunctious children.

"I don't know that they're trying to test me, I think that they truly want to do some of this stuff," the father of five said. "I think I have raised thinking children and for that I'm blessed. And at the same token, for that I am cursed."
