Some of us who don't routinely teach calculus would find it interesting 
to hear from those who do as to which "lies" are the most helpful in 
getting students up to speed on the subject.  One could then judge which 
ones are really necessary for good pedagogy, as opposed to being merely 
unexamined conventional wisdom about the subject.
