OK, I'm totally lying. This is not a clip from I Want To Believe. But a guy can dream, can't he? (It's actually the opening credits of this show, which I had never heard of before yesterday; somehow I doubt I'll be writing a laudatory Better Late Than Never column about it anytime soon.)
Found at the reliably funny blog Why, That's Delightful!, the home of writer Graham Linehan, who among other things created the wonderfully insane Irish sitcom Father Ted.
