I suppose this is one of those songs where I should start with a disclaimer that I'm not posting it for any kind of personal reason; I remain a happy newlywed. I just think it's a fun song -- a wonderful homage to 1950's love ballad, with equally wonderful lyrics that subvert the genre. But yes it was on a very long list of "Zappa Songs I Should Not Put On My Wedding Playlist". Hell, I think the entirety of Freak Out! fits that description.
And if that's not enough, this is a great damn cover, by one George Possley. I couldn't find a good copy of Frank and the Mothers performing it themselves (aside from actual album rips, which, again, I prefer not to repost), but it's just as well, because I found this.
