As many times as I've seen this ep, I don't know why it suddenly struck me as odd today when I saw the wooden wheelchair:

Did they still use those back in the mid-'60s? I know when I was in the hospital back around that time I never remember seeing any. The ones I saw/were in were mostly canvas/metal and nicely padded.
But then, considering all the smoking going on around an oxygen tent, I suppose a wooden wheelchair isn't the first thing you're going to take notice of as odd. [hall2_grin]
