Funny story about this one.
Mrs. 8893 and I finished The Queen's Gambit on Saturday and we agreed that this would be our next series. I asked her what channel it was on and she said she thought it was on Netflix. I checked Netflix and didn't see it, and then I thought I remembered it being on Showtime, so I just used the voice control on our Xfinity remote and said "The Undoing." It offered me an HBO viewing option so I clicked it without looking at the details.
It immediately brought me to the scene where they show the murder. I thought, "Huh, that's strange; must be one of those deals where the whole series is a flashback." We watched until the bridge scene with the helicopter and Kidman rescuing the kid.
And then it hit us. We must have tuned to the end of the final episode, which was being shown live on one of our HBO feeds.
I started bursting into uncontrollable laughter at the absurdity. Mrs. 8893 was not quite as amused. She was in shock, and I kept laughing harder the more astounded she was.
We did find it On Demand and watched the first episode, during which I couldn't help editorializing based on the forbidden fruit we had already eaten, frequently punctuating my comments with a maniacal laugh.
I've had at least a half dozen more spontaneous laughs about it since. We're still going to watch the series and she will never let me live it down.
