As is so often the case, the title today explains the trick, but as is also often the case, it's not easy to see how it does explain it until you've actually figured out the trick.
So anyway, some of the silly new phrases are pretty funny. ABSOLUTEPOW (Perfectly placed "Batman" punch?) has a nice nostalgic element, and HAPPILYEVERAFT (Always glad to be seated in the back of the boat?) is amusingly absurd. Why isn't CELLPHONENUMB (Having no feeling in one's texting hand?) as funny to me? I'm not sure. Maybe because the leap from hand to cellphone is too great? Or maybe just because it involves a cellphone at all? But most of them at least got a smile, so that's good.
But speaking of smiling, I didn't do any of it when reading 8A: Developer of 1982's E.T., a video game so bad that hundreds of thousands of unsold cartridges were secretly buried in a New Mexico landfill (ATARI). I have many questions about this, but I'm not going to look into any of them, because it's the weekend, and I'm in the middle of a vacation, and I just don't need that kind of aggravation right now. That kind of waste is NOLAUGHINGMATT! :)
And speaking of waste, I liked the two "straw" clues: "Drink rarely drunk with a straw" (ALE) and "Drinks usually drunk with straws" MALTS. Mmmm.... MALTS... I usually get one a year, and this year's is still to come! Maybe it'll be today!
Lastly, I found it interesting and appropriate that CAVITIES and FENESTRA were symmetrical.
It was a fun, quick, solve. I'm maybe still not in a crossword UTOPIA, but we all knew I'd never get there anyway.
