Mountain Dew

Anyone remember this one? I was at work yesterday and somehow the topic of Mountain Dew lowering sperm count came up...obviously I know it's not true, but I distinctly remember the boys in my 5th grade class being deathly afraid of yellow number 5 dye and Mountain Dew. I decided to see what Snopes.com had to say about it and it's origins. Unfortunately it doesn't have much to say about how the rumour originated, but it has some funny variations of the story...
