On Food Network Eroticism

I've noticed a trend in some of the shows I watch on the Food Network. On Ina Garten's and Giada De Laurentiis' shows I've begun to pay attention to a scene where each of them will determinedly turn on their sink faucets, squirt soap, and scrub their hands to rhythmic music. It's rather sensually done and hardly relevant to the day's recipes. I suppose, on some level, the shows are just encouraging good hygiene practices in the kitchen. But, if it's all about cleanliness, why do I feel so dirty when I watch?
