I recently had some Mountain Dew and it brought back fond memories of when I was boy. I was surprised at the amount of caffeine in it and the "charge" it gave me.
Now I drink it all the time at work and my production has gone up considerably. I am a carpenter so having the extra "charge" during the day helps.
I don't know anyone else who drinks dew and I thought it was funny to see it referenced to wow players.
