Providence Season 1 Episode 10

Syd: This is the big moment. The classic thirties crash kiss. It's a wonder he doesn't break her jaw.
David: I guess they don't really do it that way anymore.
Syd: No, they lightened up in the fourties and fifties.
David: Softer kissing.
Syd: And in the sixties there's a European influence. Less lips, more tongue.
David: The French kiss.
Syd: In the seventies and eighties they moved from the lips being the primary target to other erogenous zones such as the neck and shoulders.
David: And what about the nineties?
Syd: Bad news. The kiss becomes an endangered species, eclipsed by other forms of passion.
David: Less kissing. That's a shame.
Syd: See, that makes the kiss more special, you know, reserved for the most passionate moments.
David: Like this?
