Well, to go with the phallic imagery in this one, they'd have had to abandon the racist stereotype of the drum-beatin' injun. And the drink's CALLED "Indian" so they aren't gonna do that.
Also, it's acceptable for a woman to ride the bottle forwards while it explodes, but not for a man. You can't ride the dick-symbol if you've actually got one. Not on daytime television, anyway.
I'm betting the original idea had the warrior cougar on forwards but the test take told them that might be taking this a bit too far (not that it isn't already out in the stratosphere)
