Well... Episode 69 is live. And, finally, last night, I freed my chair from the final knot which had proven trickier than it should have. I fiddled with it absently a few times over the last day or so as I sat at my desk. But finally, it was annoying enough to be tied to the knob of the cabinet that I gave in... and turned the chair on its side so I could get to the knot from there (since the knot on the knob had proven impossibly angled under the curve of the knob for me to get it free).
So, what happens? Well... three of the casters (wheels) fell off, of course, which is why I hadn't taken that approach at first.
It's one of "those" kind of chairs. You lift up one part to fix a wheel, and another wheel falls off. Funny - but annoying.
At any rate. The chair is (temporarily free). The show is live. And... another week goes by!
