Pee-foam Green

Great to Be a Guy Reason #174: When guys pee into a toilet with those tablets that make the water blue for 1,000 flushes they are granted the profound pleasure of watching the blue water turn green as they pee. This is because they have penes and pee standing up and can watch the whole thing. Girls only get to see the finished product because they have vaginas and pee sitting down, sometimes with their legs crossed if they are wearing a dress.
