I have a friend named Stacy, and she's black. When she was growing up she noticed a correlation between the color of her skin and the color of her poop- to a younger kid, it made lots of sense that the correlation extended to everyone. Hence, for years she was under the impression that black people pooped brown poop and white people pooped white poop.
A childhood belief about weeing and pooing

others believed things like this
- My poop was always around the same color as my skin so I assumed white people's poop was white.— jaycee
- I'm black, so as a child I used to assume that white people pooped peach the way I pooped brown.— Rick
- 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 used to believe that white people had white poop and that mine was brown because I was brownAnon
- I used to believe that before color television, people only saw in black an white.— CD
- Brown or otherwise non-white snow was snowman poop. My kids believe it too!— Dellio
