This is the second half of a two part season finale originally broadcast by NBC on 15 February 2008. The story lines for part one and part two are completely disjoint from one another.
The title of the episode is a reference to the 1994 movie Four Weddings and a Funeral.
According to NBC, this episode was to serve as the series finale upon the series cancellation in February 2008. Unfortunately, there is one unresolved cliffhanger that arises: Delinda's baby. At the end of the episode there is a computer graphic overlay that says, "To Be Continued..." There is an effort being made to produce at least one more episode, possibly a two-hour special, to wrap up the series properly.
James Blunt: I thought this was supposed to be a wedding?
Danny: Uh yeah. Slight change of plans. You don't happen to know any sad songs?
James Blunt: Sad songs. Yeah. You're kidding?
Mike: If I tell my mother I got married without her I'm a dead man.
Danny: So what are you going to do?
Mike: Told her the wedding is this weekend.
Danny: You're throwing a fake wedding?!
Danny: Oh my god, that's genius!
Mike: Will you fake stand up for me?
Danny: I'd be falsely honored.
