Oh my! Thanks so much, redundantelf et al. I just watched the great clip (the surgery- yikes!). "Column" was, not surprisingly, used a number of times (julianandsandy's "entry" made me roar; I assume that's you, rambler, you nut), but it's hard to avoid (uh, sorry, jands) something so tempting. Fine clues all around. I'll start cogitating now...
