This is tangentially related.

I went to college with this kid, C. I say kid because I was 24 and home from Desert Storm and he was fresh out of High School. C was a good kid, but a full on nerd. Not in a bad way. I’m a nerd too. We met in the smoking lounge at my college where we played Magic the Gathering (back in Alpha and Beta days) in between and sometimes during classes. But I digress.

C carried to school every day 2 two liter bottles of Mountain Dew. He had been drinking it so long and had been neglecting his teeth so long that they were black and yellow.

One day C meets a girl. She is not very pretty, but C has never had a girlfriend. He starts to eat better. Loses wait. Cleans up his teeth. Gets laid. Is much more confident and happy.

Then he isn’t. She left him for another woman after a few months. The humiliation he felt sent him deep into the Mountain Dew bottle again. He packs on the pounds and actually gets worse. He now brings thousands of dollars of Magic cards to schools every day, becomes a total incel and flunks out.

Moral of the story: Mountain Dew is evil.
