We just watched Blazing Saddles. Gene Wilder will be missed and loved. So funny.
I was amused by this theme. It works really well in three out of the four answers, and the fourth one is pretty good too. You add "it" to the end of a standard phrase to make a new silly phrase. And the revealer is MAKEITLAST... get it? or should I say get "it"?
The idea works best when the addition turns the last word into another word, or reconfigures the phrase to mean something entirely different. Thus SWINGBANDIT and EMILYPOSTIT in the first sense, and SHORTSTOPIT (reparsing shortstop into short "stop it"). YESWECANIT changes the sense of "can" from "able to" into "put into a can" so that's pretty good. Just not quite as good as the other three.
It's a 78-word grid, which means there isn't a lot of room for longer down answers. But we do get both LEGSDIAMOND (full name gets extra credit) and IRSAUDITORS, which is pretty fun (not in real life, you understand). Both of those answers are next to two 7-letter answers. I like BEAHERO - it took a while to figure out where that was going.
ELOI makes another appearance. Methinks it's time this hoary bit of crosswordese went the way of the dodo. In other news, ANO becomes a partial, weirdly. My error came at 47 down, where I put EMt instead of EMS. ROSEt didn't look right, and it wasn't. Should have figured that out.
1A: Sty fare (SLOP) gets a B-. It's a terse clue which improves pig food. On the other hand, all that slop turns pigs into bacon... Okay, I talked myself into a B. It was also the first answer I entered.
I'll give it a thumbs up.
