Wow! I can't think when I last read a farce, let alone enjoyed one. Probably it was Noises Off. It's difficult to maintain the suspension of disbelief in a text; in a play or film the pace of the action doesn't give one time to consider just how silly, how contrived, how unnatural the whole exercise is. And because Frayn is very skilled, he keeps one from dwelling on how absurd it is, while never forgetting for an instant just how absurd it is.
I don't think I actually laughed out loud, but I loved every silly minute of it.
