you can say what you want about vanilla coke, but didn't Pepsi come out with some sort of nasty blue raspberry flavor? It was the first time they didn't copy cokes flavors.. and it tasted like sickness.
EDIT aha! precious proof! http://en.wikipedia.org/wiki/Pepsi_Blue
*shudders* i still have nightmares about that crap
(holy crap i read that article and jesus christ they just didn't know when to give up on it, it failed EVERYWHERE)
i pref coke mainly because of the pepsi ads on tv. you see i'm a very spiteful person so when i see a pepsi ad on tv insulting coke i go "fuck you, just for that imma go buy some coke" and so i never buy pepsi because of the tv ads. in fact any time i see some product or another insulting other products to help their sales i go buy the product they are insulting
not only that but coke is the original ,pepsi came after.
oh and of course don't forget my fave tv ad ever was made by coke "put the lime in the coke you nut" *starts bobbing head as he sings it. stops, looks around sees everybody watching him* ehehe *sweat drop*
