I'm not even going to bother looking them up... but I'm sure the words "we stand on God for thee" is not anywhere in "O Canada."
Unless, of course, a Canadian's devotion to country is so strong that one would, in fact, trample a deity for it. If that's the case... then I stand corrected.
UPDATE
So noted Canadian... and really one of the premier young NBA writers out there... Holly MacKenzie says I'm wrong here. I hear Shaq saying "God." She says he's saying "guard", which is the correct word. As evidence, she submits this:
I still say he screwed up the lyric and said God. Holly says I just haven't caught on to Shaq's mumble. Either way... Shaq's a goof. I think we can all agree on that.
