I learnt from this forum that "Build A Bonfire" is a United Kingdom children's taunt directed at teachers.

[I'm noting that information on this thread in case there are other Americans* or people from other nations who may have read about that rhyme and didn't get what Michael said about it not being all that original.

* Where are the Americans by the way? In my opinion, the issue of fascism is not just a UK issue. I think that Bruce is the only other "American" besides me who posts to Mudcat's anti-fascism threads.
