I shouldn't admit this. Let's hope neither the headmaster nor any deans or deanlings are reading.
I don't get Touchstone.
I don't find the part very funny. Yes, I understand and can process the jokes, adequately, I think. They just don't seem really funny overall.
But I don't know quite what to make of Touchstone and Audrey. Is she as horny for him as he is for her? And how horny is he for her? Does his horniness level change?
I'm hanging my head, clearly an inadequate Shakespeare person.
I try to imagine what William Kempe would have done with the role. (If you click on the link, they have a reproduction of a woodcut of Kempe's famous Nine Days Wonder. It's like an early modern YouTube. /nod.)
I also don't find the songs very compelling. Yes, I get how they comment on the action, sort of. But horn and cuckoldry songs just don't work in performance that I've seen.
