I thought the same thing!!! I am very short with very muscular legs, too, so I always notice when other girls have them. (Random, but I feel the same way about Melissa Joan Hart.)
And I can't say how much I love watching Derek dance! He's awesome. I remember the season he danced with Shannon Elizabeth thinking he seemed SO cocky and not liking him at all, but he's become very likeable to me over the years since then.
