No One Can Say "Rubbish" Except the Teacher

Really, I had to have that rule in my classroom.  One of the students said he didn't know how to solve a simple math problem.  I knew better so my response was "Rubbish, of course you do, answer the question".  Those of you who are thinking I was being mean, relax.  I knew he could do it, and sure enough, he did.  However, the response caught on and the whole class was saying "Rubbish" every other word.  Finally I had to make a rule: No one can say "rubbish" except me, it's my word and mine alone.

Teaching can be a blast, some days.
