I also reminded the students that I had been known to "exploit" seventh-graders as well. For example, a few of the teachers at a different school I used to work at teamed up once to convince the students that we were at war with Canada. We also told them that spaghetti grew on trees. Classic example of "exploiting" gullibility based on the classic 1957 April Fools joke concocted by the BBC:
My current students laughed and laughed....no way would THEY be so stupid as to allow me to "exploit" them in such a fashion!
Then a student asked how noodles were ACTUALLY made. Another student immediately piped up that he made noodles at home with his family and that they were made from flour. I confirmed this detail. The first student looked puzzled, so I clarified that noodles were made from eggs and flour and water. He said, "OH! I thought you meant that they were made from FLOWERS! This makes MUCH more sense!"
