It's really, really hard to pick just one. I think my favorite skating moments have been when a skater I love has an amazing skate and wins a title that they truly deserve.
That said, one moment that really stands out to me is when Irina Slutskaya won Worlds in her home country in 2005. Say what you will about Irina's skating in general, but I was absolutely thrilled for her after all she had gone through with her mother's illness and then that life threatening heart condition of her own. I think it was a true example of fighting spirit and, combined with her showing at 2004 Worlds, a love for skating.
