I have heard this on cd, but never seen it performed...and it is funny

Sometime back in biblical times, Steven Sondheim composed something for a theater festival or something at Yale and it was performed in a swimming pool, and was Aristophanes' play, 'The Frogs'. I believe that Meryl Streep was a student and was in the production at the time. (And it's a good thing my brother never reads this, because he would run for the barf bags... he never recovered from Kramer vs. Kramer...) I love the lyrics and hilarity of it, and since theater audiences have become ruder by the decade, one should take the advice to heart.
