Isn't the whole play meant to be an existential commentary on life? Basically, we're here born and then we die, and while things may change around us, we're still the same. It's been a while since I studied the play in school, so I don't really remember the specifics of Lucky's speech. He and...oh, what's his name, his master...are symbols of what changes around us, but the fact that Godot never comes, and Vlad and Gogo never leave or really change is the commentary on our lives. I always actually thought of Godot as death more than God...
And Margo's right about the comedy - I remember my professor saying something about the fact that the humor was a comment on the absurdity of life, and how we all amuse ourselves to pass the time...
Something like that - like I said, it's been a while...
