Nude yoga?

I was window shopping on Amazon.com this evening and I happened to do a search for the Mad About You dvds. I innocently typed "Mad About You" into the search field and one of the things that came up (I swear, I'm not making this up) was "Aaron Star's Hot Nude Yoga." Which leaves me to believe one of two things: 1) Someone at Amazon is having fun at my expense, or 2) Someone at Amazon needs to improve their search engine.
