Chase turns 18 and wants to be like a peacock and "fly." So his parents Todd and Julie pretend to charge him for services rendered like it's "Hotel Chrisley." "Bill or abide by their rules," Todd says.

"The prices are ridiculous and I'm leaving," Chase says. He moves to grandma Faye but then has to babysit Faye's very aged friend Catherine and buy adult diapers at the pharmacy. He lasts four hours. "It felt like four days," he says.

Here are show's most notable quips:

"There ain't nothin' open after midnight except legs and the ER. And he's going to stay out of both of them." - Todd, keeping Chase's midnight curfew despite the fact he's turned 18.

"You're not going to learn until the road hits you in the ass - and it will." - Todd, to his son as he leaves for grandma's.

"I bought diapers. I'm not about to change one." - Chase, anticipating what he might have to do at Faye's house.

"My kids are allergic to anything that resembles a job." - Todd, self satisfied when Chase returns home.

"What he realizes is he'd rather put up with my **** than Catherine's." - Todd.
