The good people at Pepsi originally took 7 tries to get their 7-Up soda right (For those of you in Canada that's "pop" of course). As far as I know Coca Cola and Dr. Pepper haven't even manged to perfect 1-up yet (though I like Sprite a whole bunch too).
Anyway, those 7-Up people have really gotten on their game and can get your number in one try now - word! Check it out below.
