I finished this one in a normal amount of time - maybe seven minutes - but did not get the "Well Done!" message. I looked through quickly for a typo, then went through every entry twice more and still could not find an obvious error. Finally, I handed it to Frannie, who read the first word in "22A: Annoyed one's bedmate, perhaps" as a verb, as it was intended, and quickly righted things. I had read "Annoyed one" together to mean "the one who was annoyed", and entered "SNOREr" instead of SNORED, since the one doing the annoying in that case would be the snorer… oh well. And an RNA lab seemed plausible to me, but now that I see DNA (23D: ____ lab), I guess it is more likely.
The theme of IMNOTADOCTOR BUT IPLAYONEONTV was slightly amusing, but I don't think I've ever seen an entire episode of any of the shows from which the four doctors were chosen. Quincy is the only possibility, as it could have been on while I was in the room, but the others are definite nos.
So, with a tepid response to the theme, I looked to the fill for entertainment, but found precious little. Lots of NYSE, ADZ, ARR, DIDI, DYAD and ONOR, and too few clever clues like 36A: Brown beagle? (SNOOPY), which I only now realize refers to the family that owned Snoopy. Not bad, really, but not enough.
It is already a banner week for 1D: Douglas who wrote "The Hitchhiker's Guide to the Galaxy" (ADAMS), though. I wonder what tomorrow's Adams clue will be?
