The episode title is a reference to the American teen drama TV series Pretty Little Liars.
At school, Lisa is inducted into a group of smart students who hide their intelligence to avoid being bullied.
When Brandine returns home, Cletus has gotten a library card and checked out Green Eggs and Ham, so he can learn to have something in common with her.
"[2] Marcus Gibson of Bubbleblabber gave the episode a 7 out of 10 stating, "Overall, “Pretty Whittle Liar’ strives in its intelligence, even though it struggles to juggle its elements into a single storyline.
The episode also offers some genuinely decent humor, including Homer lighting his fart on fire and the ‘Cletus on Books’ segment during the end credits.
