This would have been well over 20 years ago, but I still remember that a friend of mine started warning me of the dangers of sugar.
One day, I walked into a local joint and ordered a double cheeseburger, large order of fries, and a large Diet Coke. [V]
The kid taking my order actually laughed out loud, and the little sh*t had the nerve to say, "What difference does ordering Diet Coke make?"
Although I basically agreed with him, to this day I wish a pox upon his offspring!! [:D]
