In my lecture, I am thinking of using a famous quote by Winston S. Churchill:
A good speech should be like a woman's skirt; long enough to cover the subject and short enough to create interest.
I like this quote because it clearly expresses the idea that while you should go over the important details in your speech, your speech should not be overly detailed.
However, I don't know if some of the students may feel uncomfortable if I use this quote in class.
Question: Should I play safe and avoid using this quote in class, in case some students are offended?
What I decided to do
Although the Churchill quote is quite memorable, I agree with the answer which says:
Whether you actually believe that or not, telling that joke gives students the impression that you do. That perception makes the classroom environment more unpleasant for a female student and less conducive to learning.
I will find another way to express my idea without the quote.
In response to comments
Several commenters have pointed out that:
My general advice is if you need to ask someone else if it is appropriate, you already know you will get into trouble.
That is good advice. I had a "gut feeling" that it was not a good idea to use this quote; partly I asked this question because I wanted to understand why it was not a good idea.
