That game made me laugh. I thought it was a joke at first. But I have seen animal key chains where you squeeze them and poo comes out of them and then when you unsqueeze it, poo goes back in. Fake poo of course. I also remember when I was in my junior year of high school, these girls used to draw animals on the board and then make some black dots behind their behind and would write "poop" on the board. Some other kids thought that was so gross. It was mostly this one girl that did it.
My ex boyfriend used to say "I have to go poo" when he would use the bathroom. I always found it funny because I picture Pooh Bear because of the word poo. I also remember the joke in 7th grade, why did Tigger look in the toilet? He was looking for Pooh.
When we first got a miniature Schnauzer, she got constipated one day so my dad had to dig it out of her and he was telling me that story in the car and my brothers ruined it for me by telling him to be quiet about it. But my dad said he was done telling the story anyway. Mom one time dug it out of me when I was 12 because I was so badly constipated. It was the worst one ever. It hurt like heck. Then at age 16 I started to do it myself and I got used to it.
