Most jarring images
Of all of the bizarre, ludicrous and wild images in this film, including Sean Connery in a red diaper and gunbelt (or in a white wedding dress and veil!), I think the most jarring, for me, was all of the crochet!
I had an aunt who was turning out vests like these in the late 1960s:

The one that really made me laugh was the afghan hanging under the ceiling in the weaving room where May gets Zed to tell his story (and go blind for no apparent reason). I couldn't find a good picture of it, but you can see a bit of it in this pic, above the yellow arrows:
