Coke or Mountain Dew?

I agree with The Defender I heard that it had some effect on guys, but that was like 5 years ago. Some guy in my class who was a total geek, or something, said "Oh I'm not going to drink Mountain Dew because it affects the growth *-----" I'm not going tosay because its going to just hurt the Mt. Dew lovers. I personally like Pepsi. Cocacola has some aftertaste (i hope im no the only one that thinks that).
