- 20A: One debating the unpopular side (DEVIL'S ADVOCATE).
- 31A: Healer using magic (WITCH DOCTOR).
- 41A: Uncredited author (GHOST WRITER).
- 55A: Wee-hours work period for 20-, 31- and 41-Across? (GRAVEYARD SHIFT).
- 15A: Little suckers (LICE). Um, breakfast test!
- 23A: Washing aid for pupils (EYE CUP). I assume this is something used at an eye doctor's office? I'm not familiar with any sort of eye health stuff. I actually never wore glasses until I turned 40! Of course now I need three different pair and feel like a total old lady.
- 25A: "Hold on __!" (A SEC). Because "to your hat" wouldn't fit.
- 39A: About 1,609 meters (MILE). Just last night I was helping PuzzleDaughter study for a test on the metric system. Isn't it about time the U.S. just converts to the metric system and get it over with?
- 40A: Game system played with gestures (WII). We just got the Xbox 360 with Kinect. Have you seen the commercials??? It's amazing to think that someday people will look back on it and go "Can you believe how we thought that was so amazing?"
- 48A: Pitching miscues (BALKS). I recently did some research on BALKS (and by "did some research" I of course mean "read the Wikipedia article"). I pretty much can't remember anything I learned (did I mention the old lady thing?) but at the time I thought it was pretty interesting. Worth a look if you're a baseball fan and don't understand how the BALK rule works.
- 51A: Where AMZN stock is traded (NASDAQ). I plopped this answer in without even thinking, but I already had the T in place on 55A so that QT mash-up looked all kindsa wrong. (54D: Wax removers (Q-TIPS).)
- 1D: Fine porcelain (SPODE). This word looks vaguely familiar to me. I'm sure I've seen it in a puzzle before but today I needed every single cross.
- 3D: Naproxen, commercially (ALEVE). I know way too much about pain relievers.
- 5D: Held firmly (CLASPED). I tried "clamped" first.
- 31D: Guitar effect (WAWA). Yes, that's the technical term for it.
- 41D: Covers, as a driveway (GRAVELS). I guess I've been a city slicker too long — GRAVEL didn't even occur to me.
Other crosswordese in the puzzle that we've already covered:
