Having put in AVA at 1A (DuVernay who directed "Selma", gets a B+ for referencing an African-American female director and a great movie), I immediately fell for the trap of putting in Verizon, which is really not an "Internet-based phone provider" (VONAGE). Sometimes when I have entered something incorrectly, I have to move away entirely before I can see the correct entries.
My error came at the crossing of 6D: Crystal ____ (METH) and 21A: "As if!" (HAH), where I had put nAH and never came back to check it. Oh well. That's the bad stuff out of the way.
This is an odd and oddly satisfying theme today, befitting a Wednesday. The three 15-letter answers are unrelated to each other, but each is crossed by a pun that plays on the content of letters in that answer. Thus 4D: What 17-Across has, phonetically (FORESEES) is pointing out the 4 Cs found in ANTARCTICCIRCLE.
Each 15-letter answer is a solid one, and all three puns work fine, although FORTIES doesn't exactly sound the same to me as "four Ts". THATSAMOOTPOINT though. I enjoyed it.
Some really nice cluing in the fill also helped my good spirits. 25A: Daniel who created Friday (DEFOE) is very nice, especially without a question mark. Even better is 34D: Worrisome call at home (STRIKETWO). I love that sort of thing!
I'm not convinced by a single ANTLER and by multiple TESLAS. Kind of funny to have METH and Breaking Bad actress RHEA Seehorn in the same grid.
That's me, over and OORT.
