"I couldn't be happier, simply
couldn't be happier--
well, not simply...
'Cause getting your dreams, it's strange, but it seems a little, well--
complicated.
There's a kind of a sort of a--
cost
There's a couple of things get--
lost;
There are bridges you crossed you didn't know you'd crossed until you crossed...

And if that joy, that thrill
doesn't thrill like you think it will,
Still
With this perfect finale, the cheers and a bally-hoo--
who wouldn't be happier? so
I couldn't be happier
Because happy is what happens when all your dreams come true...
Well, isn't it?
Happy is what happens when your dreams come true."

Perhaps my favourite Wicked lines, from Thank Goodness--sung by Glinda/Galinda (sp?). So telling.
