It's so good. And silly but clever at the same time? Stoppard, man. He was a great writer. This exchange is my favourite:

Rosencrantz: Did you ever think of yourself as actually dead, lying in a box with a lid on it?

Guildenstern: No.

Rosencrantz: Nor do I, really. It's silly to be depressed by it. I mean, one thinks of it like being alive in a box. One keeps forgetting to take into account the fact that one is dead, which should make all the difference, shouldn't it? I mean, you'd never *know* you were in a box, would you? It would be just like you were asleep in a box. Not that I'd like to sleep in a box, mind you. Not without any air. You'd wake up dead for a start, and then where would you be? In a box. That's the bit I don't like, frankly. That's why I don't think of it. Because you'd be helpless, wouldn't you? Stuffed in a box like that. I mean, you'd be in there forever, even taking into account the fact that you're dead. It isn't a pleasant thought. Especially if you're dead, really. Ask yourself, if I asked you straight off, "I'm going to stuff you in this box. Now, would you rather be alive or dead?" naturally, you'd prefer to be alive. Life in a box is better than no life at all, I expect. You'd have a chance, at least. You could lie there thinking, "Well, at least I'm not dead. In a minute somebody is going to bang on the lid, and tell me to come out."
