Down the drain

Blake loves Pez. Why? I have no idea. He found his stash of Pez from his Gramma and Grampa this afternoon and walked up to me with four little lonely Pez candies and his squirrel Pez dispenser. After he asked me to put it together, I had to ask:

"Where are the rest of the Pez?"

"Down the drain."

"What drain?"

"My mouth drain."
