Really tough now...
18 because it's a little less stand out for me then the others
and 26....very sweet and Luke at his best but it's not as strong as the rest (totally unintentional rhyme)
I actually like 32 a lot, but then I don't really see it as typical Emily interference. I see it more as her way of showing support for Lorelai's choice to marry Luke (finally, and in her Emily way, but still). She also seems to be considering what's important to Lorelai and not what she thinks is "best" with the horses and the Stars Hollow address. Plus, Lorelai seems touched by it and there is the subtle moment where Lorelai tells Emily she doesn't think it's going to happen and Emily reaches out and puts her hand on Lorelai's shoulder. Ah well though, I see the over stepping thing too.
