Also, I hear something pony-related will be happening over the weekend. Of course, so's Easter, so we'll see if I get to it before Monday, i.e. in time to post about it when it's still at least vaguely fresh-ish. For now, though, we'll still have to content ourselves with fanfiction... so head on down below the break for my reviews of some of the good (hopefully!) stuff!
Pinkie Pie's Foray into Absent-Minded Treason, by Desavlos
Zero-ish spoiler summary: Celestia decides to make an impromptu visit to Ponyville, which naturally puts both Twilight and the townsfolk on edge. Still, they have nothing to fear, since the princess isn't prone to violent overreaction... right?
A few thoughts: Given the author's summary, you might expect this story to be about Celestia's hair, and some terrible secret concerning it. Actually, that's really just a punchline (of sorts) at the end of an otherwise unrelated comedy fic; set your expectations accordingly. Now, there are some nice bits of satirical humor scattered about this fic--and in particular it does self-referential callbacks to stuff like the frequency with which Celestia's doors get broken down very well--but they don't ever form into a cohesive or consistent whole. In other words, the thing this story is sorely lacking is a point; some narrative or thematic (and/or comedic!) commonality to tie it all together. The editing also ends up a little on the wonky side, though not to the point of interfering with readability.
Recommendation: If you find evilish-Celestia-played-for-laughs inherently funny and don't mind your horsefics on the ephemeral and random side, then this might prove amusing enough for you. I wouldn't recommend it outside of that audience, though.
Why Rainbow Dash Can't Be the Element of Honesty, by Original Usermane
Zero-ish spoiler summary: The girls discover that Rainbow Dash has a "terrible" secret.
A few thoughts: Here's another story that leans heavily on low-key randomness for its humor; the reveal isn't set up by anything else in the fic, ponies show up at random to comment on the proceedings (to be fair, this is deliberately played for laughs), and everypony's reactions are based more on what would be humorous/keep the scene going than on consistent personalities. The resulting story is one that's got a fair bit of humor in it, but it's largely of a diffuse, unfocused variety.
Recommendation: If you're looking for something light and silly, this isn't an awful choice. It's definitely not for anyone who wants more than some tangential humor which leads up to a thematic non-sequitur, though.
A Mistake in Identity, by JapaneseTeeth
Zero-ish spoiler summary: Cadence wakes up with a terrible hangover and no recollection of the night prior. Meanwhile, Vinyl Scratch has one heck of a story to tell her roommate...
A few thoughts: This is not a complicated story; it's a classic "reveal the forgotten embarrassment" fic, in both structure and event (that the structure is told from two alternating perspectives gives the story a bit of construction-level interest, but only a bit). What it succeeds at doing, however, is telling its story in a consistently engaging manner, with a quick pace, and with humor based around its characters and their vastly disparate reactions to what transpired. So while this may not be a deep story, it's very successful at what it sets out to do.
Recommendation: If you're looking for something short and funny (and it's got kissing!), then this is a solid choice. It's obviously not for readers looking for an intricate or involved tale, but for those seeking morning-after comedy, this is a well above-average example.
