Dumb New Invention

In order to avoid the exam, Dutou invented an "automatic homework completion machine". He carried the machine into the classroom and pressed the switch triumphantly. As a result, the machine spit out white paper crazily and flooded the entire classroom. When the principal arrived, Dutou was sitting on the paper mountain, holding up the textbook as an oar. The funniest thing is that the last piece of paper spit out by the machine said: The answer can be found on page 42 of the textbook. The whole class laughed like crazy. The idiot scratched his head and said, "It turns out that it can copy better than me."
