[Harriet finds a notice in the newspaper that Palisades Park ferris wheel operator Pop Gibson is in town, bringing back memories]
Ozzie Nelson: We sure spent enough time on that ferris wheel of his.
David Nelson: Didn't you do anything else at the park, Pop?
Ozzie Nelson: Oh, sure. We used to go dancing in the Pavilion, and we'd ride out in the boats on the lake, and we'd stroll hand in hand through the park in the moonlight, and we'd ride through the tunnel of love.
Ricky Nelson: Yeah, but what'd you do for excitement?
[everyone laughs]
David Nelson: Oh, Ricky, don't be such a sap.
Ricky Nelson: Oh, I'm only kiddin'.
Ricky Nelson: [he breaks the fourth wall, speaking directly to the viewers] It's kinda hard to tell sometimes, though, huh?
[he ends his little joke with a trademark, stylized throaty laugh that sounds something like an old jalopy trying to start - ahh-ahh-ahh-ahh]
