I used to believe that people with brown eyes pooped more than average (as poop is brown), people with hazel eyes did slightly more poops than average, people with blue eyes peed more than average (as blue is kind of like a watery colour) and people with green eyes did the average amount of pees and poops.
A childhood belief about weeing and pooing

others believed things like this
- I was born brunette with brown eyes and dark hair, i thought people with blue eyes, had water in them.Anon
- i used to believe that people with blue or green eyes saw that certain color— mellactica
- I used to think all people with green eyes were IrishAnon
- I used to think that "cross-eyed" meant that people had X's for eyes, like dead people in cartoons.— Tim
- when I was little I used to think that white people had pink poop (i am brown so my poop is brown)— helena muteka
- I'm black, so as a child I used to assume that white people pooped peach the way I pooped brown.— Rick
