Yup, I have been in lots and lots of plays. Mainly through my drama club, but they weren't famous plays. One of them was called Storyland.
There was school whereupon I played Zebulan in the school play of Joseph and his amazing technicoloured dreamcoat. I also did drama GCSE where I had to play all the female parts in Of mice and men (Aunt Clara etc) cos it was a boy's school!
Talking of female roles I was Cinderella in my uni's 2 minute adaption of a fairy tale and Cinderella again when I taught english in spain!! So, to answer the question, yes I've been in plays! The best ones are when you come up with the story yourself!
