When I was in a high school English class, the teacher assigned a section of Aristophanes’ The Frogs to be read aloud in class. She picked different show-offs for the lead characters, and the rest of the class was the chorus. And off we went.
We could barely get through it, we were laughing so hard. When we got into the irresistible rhythm of the piece, with the chorus, all frogs, punching the beat out with “croax, croax”, it was hysterical. I don’t think anyone in that class forgot that moment, and I’m pretty sure most of them checked out the whole play soon thereafter.
So, yeah. They were funny. But scripts aren’t plays; they just lie there until someone picks them up and gives them life.
