I've been in a couple of school plays in elementary school. I played Constable Bastian in "Folk og Røvere i Kardemomme by" (People and Robbers of Cardemon Town), which is a popular Norwegian children's book by Thorbjørn Egner. Chances are that if you're Scandinavian you know it.
I was also the ringmaster in a circus/play kind of thing xD

Also, I've seen lots of plays/musicals. I can't tell you which one's my favourite, though.
