I dunno, I thought Harrad Experiment had plenty of conflict, and it ended with a six-people marriage. (Did I mention my parents took me to see it when I was twelve? I thought Don Johnson was dreamy.)(hay, I was TWELVE)
How about Keeping the Faith, a priest and a rabbi fall in love with Jenna Elfman (well, who wouldn't?). If it ended with all of them, it has the added benefit of turning the priest from the priesthood.
Love is that condition in which the happiness of another person is essential to your own...
