Doug and his friends attend Beebe Bluff Middle School. But the sign outside the school reads "Bluffington Middle School." (This error occurs in several episodes of the television series as well.)
When Doug finds the newspaper article stating that the monster was destroyed, he mentions that it is 'next week's paper' but starts to feel sad because he thinks Herman's dead, despite the fact that he clearly stated it was to be 'next week's paper'.
