Six of the theme answers are clued Doofus, and they're all reminiscent of Three Stooges-type humor. The theme answers are: 18A: Nincompoop; 27A: Birdbrain; 48A: Dingaling; 55A: Noodlehead; 4D: Numskull; and 39D: Dumbbell. I wouldn't use any of those words, but at least one website used Doofus to describe Dubya.
The best part of this theme was the final answer. 61D: A person who is not a doofus (you). Major sucking up? Nah...I think it's pretty genuine, and it echoes the sentiments of those of us who think that if you attempt to do this puzzle, you're way ahead of someone who won't even try.
I was going great guns with one gimme after another. Most of the theme answers came to me right away... only Noodlehead eluded me, and only for a short time. I thought knucklehead would be in here. That was my father's pet name for one of my brothers. Seriously, it was said in jest and with a lot of love. Michael would probably still answer to it today.
Before I forget...I got hung up at 33A: CD players. It didn't help that I drew a complete blank on 34D: Traitor. Jeez Louise...when I finally figured it out, I kicked myself in the butt. I absolutely was not seeing that a J belonged there, giving me DJs and Judas. I had even gone through the alphabet...Budas, Cudas, Dudas. I feel like a doofus! It almost rhymes.
One more tripping spot, and it's one I've fallen into before. 53A: Airport stat. (ETD). As often as not, it'll be ETA, and that's what I had this time. But I wasn't coming up with an answer for 43D: Chicken __ (Tenders) with that A in place instead of a D. And I wasn't sure about 41A: Craggy mountain ridges (aretes), so that slowed me down a little.
Words I liked seeing in this one:
24A: English philosopher who wrote "Wherever Law ends, Tyranny begins" (Locke). I got it from the crosses, though. Don't know the name, but I like the quote.
29A: Cheri (amour). One of the few French words I know. Thank you, Stevie Wonder.
67A: Pig and poi feast (luau). Less than six weeks until Hawaii. I don't think we'll go to another luau, though...we just don't eat that much food at one time.
8D: Sound bite, e.g. (excerpt).
10D: Media executive Murdoch (Rupert).
19D: Difficult experiences (ordeals). In retrospect, this puzzle was more of an ordeal than I originally thought. Maybe a hair more difficult than a typical Tuesday?
24D: Expire (lapse). Actually, expire sounds pretty permanent...in more ways than one.
32D: Many an ex-con (parolee).
42D: Nickname (epithet). That's a word I don't think I've seen in a puzzle before.
And it's been a long day, so I'll keep this one short. Here's the grid...
...and I'll see you tomorrow.
