My first userpic was a different pic of this guy *points to icon*, David Ayers, who played Fiyero the first time I saw Wicked and is one of my favorites. I made it my default because my username came from his character so I thought it made sense.

My current default is my Rent "No Day But Today" icon, which became my default when the news about Rent's closing was released and I decided to keep it as my default until that sad day, and maybe a while after as an homage.
