Reading Is a Fundamental Case - S4-E12
Continuity mistake: In episode 11, Earl's list item was to give back the blue door, but in this episode he still has the door.
Suggested correction: That's because the episode was aired out of order. This episode was the 9th one produced (production code 4ALJ09), but aired in between the 12th and 13th episodes produced.
Continuity mistake: Earl is crossing Kenny off his list; he goes to Kenny's house where he lives with his parents. It is revealed that Kenny has a mom and dad. Later on the series, Kenny says he was raised by lesbian parents.
Suggested correction: Wrong show, Kenny has a Mom and a Dad. It was Raising Hope where his character had two lesbian moms.
