What You Don't Want To Hear Coming From the Bathroom...Other Than The Obvious

So tonight Josh was giving Sam his bath as I was in the den when I heard Josh say:
"Now I know why babies drown in the tub."
WHAT?!?!?
Apparently Sam was playing bathtub basketball and went to lean back and just kept going backwards until he was flat on his back in the water. His face was not in the water but he just looked up at Josh like "Now what?" and made no effort to sit up! Thankfully this was a funny incident instead of a scarry accident.
