Inu Yasha… the very first anime I realized what fan service was. Interesting enough I had to choose this image for the page because of this. I remember going frame by frame at 13 years old with the VCR and seeing this scene for the first time on tv.
FUN FACT: Later on when I would eventually record over the tape, losing the evidence. They never showed the scene again, mysteriously it disappeared off the TV airing when I recorded the episode again.
