4 aren't enough

So we have 4 bathrooms in our house.  All of which are easily accessible from anywhere you may be.  Well one of them was being used by Kid #1 and Kid #3 needed to go as well.  Wanting to use the same bathroom he went in to move along his sister so he could use the same toilet.  She was not moving so instead of suggesting one of the 3 empty toilets she tells Kid #3 to use the garbage can right next to her.  Yes, thats right the garbage can.  I heard them arguing and Kid #3 came up to tell me he had done the deed in the garbage can.  I asked Kid #1 if this was true and not just a story Kid #3 was sharing.  She confirmed my fears and I had to assess the damage.  You know what Kid #3 has great aim!!
