What is that SMELL?

Noah walked into the kitchen, sniffling his little nose like a dog. He searched and searched all around the kitchen, obviously trying to find something smelly. He finally stopped at the trash can. "I found it!" he proclaimed. He then informed me that there was a yucky smell and that he had found it in the trash can. Then he said, "Mommy, this trash can needs to brush it's teeth, it is stiiiinky!"
