The camera is close up on Waras big size 10 feet and I lightly tickle the tops of her feet and the tops of her toes while she giggles softly, her giggles evolving to steady laughter as the clip progresses and I zero on her weak spots, which turn out to be her ankles and especially her toes. I use a paper clip and spikey comb to weave in between her toes which drives her crazy!
