Why....
Didn't the two ever flush? I love this movie and that's the only thing I remember from seeing it when I was a kid.
Also, who pees that fast?
Just saying.....
The little boy did not flush but his father after him did. This is not so unusual considering the young age of the child, and that sometimes people don't flush for only pee when trying to conserve water.
What bothered me was neither washed his hands and then they went straight into the kitchen to make breakfast!
