Betty: Oh, Wilma, do you think 20 brontoburgers are enough?
Wilma: For Fred, yes. We can eat something else.
(Fred finally gets himself unstuck from the car)
Fred: I'm out. (notices the group hanging on a branch over a cliff) Hey, what are we doing up here?
Barney: That's a good question, Fred.
Wilma: Got a good answer?
(The police officer looks over the cliff and sees the Flintstones and Rubbles with their car hanging)
Police Officer: Well, I'll be.
Fred: Hooray! We're saved!
Wilma: Yoo-hoo, officer!
Betty: Thank goodness you're here.
Police Officer: Hey, don't you know it's illegal to park down there?
The fifth season DVD set again has the opening and closing credits a bit wrong. The scenes of both the families going to the drive-in and coming home are correct, and the Rubbles are finally in the car when the families leave. However, the theme song is incorrect. You can hear the "stereo" version on the introductory page of the DVDs, but the episodes themselves still have the regular version.
This is the first episode to air with Gerry Johnson as the voice of Betty Rubble. Her first episode was P-115.
When Fred and Dino meet Hoppy for the first time, they both think he is a giant mouse. A situation not unlike that of Sylvester when he occasionally came face to face with Hippity Hopper.
