Well, I'll dispute it... "The Body" didn't touch me as I didn't mind Joyce dying (I know... that opinion probably doesn't mark me as a nice person, but that's how I felt). I have to admit though, having just recently rewatched the entire S5, that this ep definitely has one big point in its favor: natural causes, a real-life situation without anything supernatural in it (if you leave out the vamp in the morgue, that was hardly more than "ok, we know this show's about vampires, so here's one for you guys who absolutely can't do without'em"). This was a major issue in why I disliked both "Ted" and "Gingerbread", both of which could have been milestones of the show if they had left out the demon and the robot.
So, here's my list:
Saddest - Tara getting brainsucked by Glory (even more intense as it happened immediately after her argument with Willow)
Most empowering - the Scoobies standing up for Tara at the end of Family
Funniest - Xander as Dracula's "Renfield", and pretty much every single second with the Buffybot
