Best FF That Manages to Be Funny Despite the Inclusion of Multiple Shootings, Angsty Misunderstandings, and Freud: Eight Sessions, by Speranza. Due South, Benton Fraser/Ray Kowalski. Picking a single humorous story from this fandom was tough; there's so many to choose from. I went with this one because I love, love, love the way Ray and Fraser handle their therapy sessions. I laughed myself dizzy. This could be just my innate fondness for therapy humor, or - no. This really is that funny. And the story isn't only humor; there's actual plot and actual seriousness and actual smut here, too.
Best FF That Will Change the Way You Relate to Egg Products: Demolition Woman, by Betty Plotnick. The Sentinel, Jim/Blair pre-slash. Again, this was a difficult choice. I'm not sure if it's the TV aspect or the cop aspect that gives rise to all the humor in these two fandoms, but I'm not complaining, even if does make my choices hard. In the end, I picked this story, even though it has been rec'd to beat the band, because I wanted to do my small bit to ensure that every living being on this planet had read the world-famous omelet box scene.
Best FF That Works Really Well as Therapy for Those Who Have Read Too Much HP FF: A Matter of Convenience, by debchan. Harry Potter, and that's all I'm gonna tell you about it. Except to say that I love this story all the more for existing in a fandom where attempts at humor are few, and successful attempts are even rarer. Also, a hint: if you write HP FF, and the beginning of this story essentially reads like a summary of your favorite plot devices, you might wanna think of branching out, mmm?
Best FF Featuring Love Poetry and Legolas: Nine Men and a Little Lady, by Kielle, aka _redpanda_. Lord of the Rings, assorted pairings. Again, this is oft-rec'd, but I want to do my part. Because, lord, humor in LotR is even rarer than humor in HP (which makes a certain amount of sense, as the canon isn't exactly giggle-a-minute, either). And we all need to read stories with endings like this one.
