If you like f/f nylon foot massage and nylon foot shots then it is a good quick scene. I didn't think Meredith scratched that hard to tickle her. Meredith had a more see-through pair of nylons on than Elisabeth.
It was an awesome seen (better if she wasnt wearing socks), but had there been even a glimpse of a ticklish reaction I would have saved it. I guess we saw it differently.
