hart to hart moment

When in a very romantic moment with a lover, out of nowhere something very absurd happens to ruin it. Based on that crappy TV show or movie (or whatever it is) called Hart to Hart.

(middle aged, semi wrinkley but still beautiful man and woman are liplocked in a sunny park when suddenly a dead body falls out of a tree.)
Man: Oh Shit Bitch!
Woman: What a mystery!
Man: This is a Hart to Hart moment, dear!
Woman: ...what the hell are you talking about?
