- I love AUNT SELMA, who is [Marge's sister, to Bart Simpson]. Mind you, I don't know which one is Patty and which one is Selma, but does it matter?
- SIGHT UNSEEN is [Not a good way to buy a car]. For a brief geeky moment, seeing TUNS in the circled squares made me hope the theme involved obscure units of measure known best by crossworders.
- NO GUTS, NO GLORY is the [Risk-taker's credo]. I'll bet that's not actually true. I bet there are some gutless people who managed to reap some glory anyway.
- The MIDNIGHT SUN is a [Seasonal Arctic phenomenon].
- That [French river valley with many chateaux] is the LOIRE.
- [Shout at a soccer game] can be GOAL or, of course, "Olé, olé, olé, olé." Or south of the border, "gol" or "goooooooooool."
- An Old English word for a [Crucifix] or cross is ROOD. Did you ever read "The Dream of the Rood," the Anglo-Saxon poem?
- [Outback runner] and [Outback hopper] are EMU and KANGAROO, respectively.
- URSI, or [Bears: Lat.], does not show up often in crosswords. Anyone try to plug in URSA at [___ Minor] instead of ASIA despite the other Latin bear?

I'm surprised to learn that there was ever an OREO Fun Barbie doll. Top-notch fill all the way around in this Sun puzzle, from AM RADIO and the SUN BELT to CRAYOLA, "I'M GOOD," and HARLEM.
Updated:

An ATTRACTIVE DEAL is a [Temptation for a business exec].
[Getting on in years] is BECOMING OLD.
A good [Chunk of change] is a PRETTY PENNY.
FETCHING STICKS is [Fun for Fido], but British vets say it's dangerous.
I don't think all the theme entries quite make it as stand-alone phrases. For example, playing fetch works better, but in this theme, the beautiful words come at the beginning. EMOTE is clued as a [Director's cry to an underactor?]. I recently read a couple articles that used the word. In one case, emoting was a good thing for a singer to do. In the other, when he felt the actors were going too far, a director cried "Emote! Emote!" to mock them into reeling it in a bit. There are several numbers hanging out in this grid: one [Till compartment] is TENS, which at first I thought would be ONES, but ONE is a few words away, clued as [Ace's value, at times]. There's also a TRIO, or [Small jazz combo], and an [Egg purchase] of a DOZEN. Yesterday, I bought my first half-dozen eggs, which I should've started long ago because I seldom finish a dozen before they're long expired. The nautical content doesn't goad me by skewing obscure, for which I'm grateful; there's just a CHART, or [Marine map], and STERN, or [Back on the ocean?]. The cruise ship I sailed on last month labeled the ends "forward" and "aft"—no bow or STERN in sight.

- CEMENT MIXER is a [Construction site turner]. Technically, we're probably supposed to call it a concrete mixer since cement is but one ingredient in concrete, but I think most of us call it a CEMENT MIXER anyway.
- METAL MAILBOX is a [Heavy-duty letter holder]. Is this a "thing," a stand-alone concept?
- MARIO LEMIEUX is the [NHL Hall-of-Famer who co-owns the Pittsburgh Penguins].
- AMENDMENT IX uses the IX to mean 9 this time. It's clued [Part of the Bil of RIghts that addresses the Constitution itself].
