I used to believe that if you drank while peeing, it would go straight through. At age 4, I decided to try it. Of course I found out that I was wrong. The bad part was that I wasn't very coordinated at age 4. Trying to drink water while standing to pee resulted in me peeing on the floor and getting a spanking.
