Although I did not notice it before or during my solve, I saw immediately after I finished that the grid today gives away, with black squares, the answer to 109-Across (Critical message that's a hint to the six longest entries in this puzzle) - SOS. The three letters start each word in the six longest entries, giving results such as STARTOUTSLOWLY, SAMEOLDSTORY, and SNAKEOILSALESMAN. It's funny to see that last one so soon after having "snake oil" in Thursday's puzzle. Still, it's a fun entry, and probably worth the double-billing. Also, how crazy is it to think that SULTANSOFSWING came out in 1978? That was so huge when I was in high school. Of course, SAILONSAILOR is even older, from 1973, but nobody remembers that one. :)
The solve went right along for me today (At 13:33, it might be my fastest Sunday ever!), which felt nice after yesterdays debacle. And I chuckled at several points along the way, which is always a good sign. Right off the bat we have PASSRUSH (1A: It might end up in a sack) (It's a football reference, Dad), and off of that I also enjoyed "2D: They have lots for sale" (AUCTIONS). I was misdirected by "18D: Rear" (PARENT), and chuckled at "97D: House of cards?" (CASINO).
As Frannie pointed out to me just now, it's a little odd that AVENUE (124A: Course of action) crosses AVE (117D" "____, Imperator!"). Of course, the latter is pronounced "ah-weh," (which is still not the same as AWE), so really, it's totally different. And speaking of Frannie, she also liked "99D: 'Wheel of Fortune' sextet" (RSTLNE). (If you don't know, those are the letters that are automatically given to the contestant at the start of the final round.)
Grid art seems so appropriate for a Sunday puzzle, doesn't it? With that, the fun entries, and the decent and not too overdone theme, I give this one a thumbs up.
