Velma.

S watching Scooby Doo this morning...                    

Mom, do you know why I like Daph-a-ne so much?  

     No, why do you like Daph-a-ne so much?
Because she's so pretty.
Mom, do you know why I like Velma so much?
      No, why?
Because she's smart like me.
And Shaggy and Scooby because they're funny. And Freddy too (?).

Sooooo glad she's identifying herself as SMART!
