The Sticky chewing gum

Once there was person who liked to chew chewing gum. He chewed chewing gum at home for breakfast, lunch and dinner. He chewed it at school at fruit break, lunch and recess. One day he accidentally bought the wrong chewing gum without looking. It was very sticky like a super glue. Now he couldn't eat anything. He went to a professor to check out what could stop the gluey chewing gum by talking in sign language. The professor gave him a glue destroyer, a paste that could stop things sticking to each other. Now he could freely open his mouth and he never liked to chew chewing gum again.
