The police, which was a paper ruler found in IKEA, went on a search for David the plastic ruler. The other plastic rulers put more and more sand on David, but he found a way out. He went into thr deep deep forest, where there was a legend that wolves would appear when there was a full moon...
So as he went into the spooky and spine-chilling forest, he saw a hut. in which there was a Bunsen burner. The Bunsen burner saw him and welcomed him in. He drank a cup of tea and fainted...
Mr. Tse, the owner of the hut, picked up the plastic ruler and decided return to the village and teach his student science with his plastic ruler, David. When he was teaching his awful students in the science lesson, he lied,"This ruler is the best ruler, better thn any of your ruler. it is over 50 years old." But his students were so naughty that they put the wooden ruler over the flame of the Bunsen burner. He was burnt.
The Bunsen burner was the one from the hut, who was picked up by another science teacher there. In fact, the forest is full oscience teachers, and it was they who would turn into wolves when there was a full moon.
Now back to the topic. The Bunsen burner was so sorry that he had burnt his friend, so he told the police. (the paper ruler found in IKEA)
