YEP, I'M YELLING.
FOUR SECONDS OFF!
I'm done now. You can take your fingers out of your ears. Really.
But, seriously, folks. Fastest by far for a Monday, beating my former fastest by nearly 20 seconds. The puzzle is straightforward, although it kind of breaks up into three separate sections. Since it's a Monday, that doesn't bother me as much. The NE to SW stretch is nice and open.
The theme is pretty loose: standard phrases where the second part only is a kind of CHEWTOY for a dog. I like 35D: *Inaptly named part of the elbow (FUNNYBONE) the best. I also like how the theme answers are placed: by crossing two in each corner, that open diagonal section is almost like a themeless. The center is particularly nice, with SKEWERS, HERESY, and KARMA. You also get the nice long downs at 15D: Mass assistant (ALTARBOY) and 33D: "Where does that guy get off?!" (THENERVE), my favorite clue-answer pair.
There are some strangely weak crossings, such as AVID and AVIS, DINER and DINERO, ONUS and OPUS, NEW and NEWT (!).
I enjoyed ATTILA next to Dan'l BOONE next to CONEY Island. A very strange juxtaposition, those three.
1A: Liberals, with "the" (LEFT). Well, I don't like having the "the" in the clue, so that knocks it down a few grades. I'll give it a B-. Feel the Bern!
