What is this 'Pepsi' you speak of? There is only Coke. To speak otherwise is a sign of mental instability. Perhaps you should report to your local Disney re-education center, citizen!
I must be the only one without a preference.....I drink Diet Coke for awhile until i need a change, then drink Diet pepsi for a change....every once in awhile between the two I buy Diet Dr.Pepper. Or maybe i have commitment issues...j/k
