Here's how it works: you turn a little switch to send the water
from the sink to the shower. Then you get out of the
shower, dry, put on your clothes for the day, and go back in to
brush your teeth. When you turn the knob on the sink to
wet your toothbrush, you get drenched by the shower.
Then you brush your teeth, change your clothes, and listen to
your spouse laughing.
