Put in Peta today for PICO (66A: Micro : millionth :: ____ : trillionth) and had a grand old time figuring out what went wrong when the "Congratulations!" didn't appear. Well, that's the way it goes, I guess. Sometimes you have to DIVEINHEADFIRST (17A: Attack an endeavor vigorously) in these situations. And sometimes there's water in the pool, and sometimes there isn't. Just ask Teddy.
Those willing to TAKETHEPLUNGE (37A: Get hitched) today will find some ARF-worthy fill, sure, like IVS, REY, AHIT, ANAP, and OLEOS, but if they just HANGINTHERE (26D: "Don't give up now!"), they'll also find such lovely words as MODISH (1D: In fashion), MEDIEVAL (8D: Pertaining to the time of castles and knights), AVENGE (46D: Exact retribution for), and the SEVENDWARFS (3D: Title characters in Disney's first full-length feature). Interesting trivia in that last one, both in the "first full-length feature" part, and in the plural itself. "Dwarfs" is, apparently, the standard plural, according to the Internets, and "dwarves" was invented by none other than J. R. R. Tolkien. Who knew?
Overall, I guess it's fine. Maybe a few too many gratuitous plurals and partials to be a great Monday, but it was at least serviceable.
Tomorrow Colum takes over again, so if you've grown weary of my reviews, you're in for a treat!
