Fisherman's Rib?

Yesterday, when at the Brooklyn Museum of Art with Jess, we spied a woman wearing a gorgeous scarf in what we believed to be fisherman's rib. We were stuck in line for nearly an hour, so we had ample time to examine her sky blue neckwarmer from afar and though we never did tackle her and ask whether or not she's a knitter, and if indeed she is, did she knit her scarf, and if she did, what yarn did she use and was that indeed fisherman's rib. Though Jess's husband did make a humorous suggestion that we merely walk up to her and say, "k, p, k, p, k, p" and if she responds in like, then she must be a knitter and we could go forward with our questions.

The reason we were so curious whether or not it was indeed fisherman's rib is because I was trying to do fisherman's rib about a month ago (before the knitting retreat which, yes, I still need to blog about...) at Jess's house and we were so confused by the directions (knit 1 below? huh?) that we looked it up online and numerous bloggers were posting about how much yarn it took. Apparently the pattern eats yarn like Cookie Monster (or my cat Atari who before my holiday party decided to slurp a six inch piece like spaghetti which sent me into panic mode for nearly 48 hours as I feared she would die from swallowing it.)
