the revenger's tragedy by thomas middleton (debately by cyril tourner, but probably not). It was written on the back of the shakespeare era and is a total pisstale on the tragedies of the time - so much backstabbing, murder, betrayal, sex, too funny.
the importance of being earnest is pretty funny too.
i also liked pygmalion by george bernard shaw, but i hated how they changed it into my fair lady... she sooooo shouldn't have ended up with him.
i haven't read many plays lately, definately not ones written recently, so i hope it helps
