Not technically the opening
But the entrance of Martin Sheen on the first episode of The West Wing. "I am the lord thy god".

Oooh...

I used to love this one as a kid.

Then I got the DVD a few years ago, and it turns out I still know all the words...
Apologies for the poor quality, I couldn't for the life of me find a decent one that wasn't a fanvid.

This is pretty awesome too.

Got to be this one
Huge machines? A hude explosion at the beginning? A cool baddie with light up eyes and mind controlling powers? Everything you could ever want from a TV show was promised in this intro, and it delivered.. www.youtube.com/watch?v=9RzCB3VRruE
