Continuity mistake: When Bobby is trying to convince Hank's friends to join the abstinence club, and when he asks Boomhauer he just stays silent. Bill then signs up and gets one of the cards Bobby has. As Hank starts to talk it goes to a close up of him but in the next shot Boomhauer is looking at one of the cards. Bill still had his card so where did Boomhauer get one of those cards?
Continuity mistake: As Luanne is becoming a "Born again" virgin, she yells after being dunked in the water. She yells "I'm a Virgin." and there is a shot to the left of two guys in the distance playing Frisbee look behind to their left. The shot sees them from the left meaning they were to Luanne's left. A few shots later Luanne is getting out of the lake and one of the guys who was playing Frisbee comes up to her from her right side and the other guy follows him. There wouldn't have been enough time in the scene for them to get all the way over to the right side of the field and not much reason to either.
