I just have to give a couple of examples, and these aren't even bad ones.
At two to three years old, I would love to take my pants off and sit on our cat just to I could feel the texture of the fur on my butt. I have only vague recollections, but I do remember that the cat would just lay there. I cant imagine it would be too pleasant but he never did anything to escape or other wise get me off him.
When my sister and I were younger, we'd poop in the tub occasionally. We'd hop up and put our feet on the edges of the tub, since the rim went all the way around, to get ourselves out of the water and scream "ALLIGATOR! THERE'S AN ALLIGATOR IN THE TUB."
Finally looked at that site. Some of it horrified me, and some of it made laugh out loud.
For some reason, I fixated on this one. It's funny, but rather charming, too:
When I was little my mom bought me one of those childs' toilets for kids who were too small to use a real toilet. She says I absolutely refused to use it because I thought it was for squirrels. Squirrel toilet.
