Favorite plays.

I'm currently a theater major and acting on stage all the freaking time now. In this time I've read/been in a few damn good plays. What are some of your favorites?

Me:
"Art" by Yasmina Reza
"True West" by Sam Shepard
"The Pillowman" by Martin McDonagh
"The Lieutenant of Inishmore" by McDonagh
"Anima Mundi" by Don Nigro
and "Proof" by Dave Auburn
