My roommate is sort of fat, not obese, but overweight. He drinks a shitload of soda. Anyway, he refuses to flush the toilet after he pees and, although this is disgusting, it has led to an incredible discovery. People with overwhelming amounts of sugar in their diets produce bubbly pee. Bubbly. Yes, bubbly. There are bubbles in the toilet. I know this isn't scientific but here are some facts.
1: I try to differentiate the soda times from the non-soda times. It's not hard. He's like an alcoholic with soda. Bubbles occur during soda times.
2: There have been times when I haven't flushed, not for the purposes of this study but for the purpose of who-the-f***-cares, and my pee has never been bubbly.
3: He's a religiphile (obsessed with god and such) and maybe that has something to do with the bubbly pee. There might be disciples or fairies or unicorns in the pee that make it bubble up.
4: He might have a disease. Hope it's not contagious.
Long story short, I hate my f***ing roommate and I hope his fat, bubbly-pissing ass will just make an exit.
