I liked this phrase in the text! it pretty tiring task to gain the attention of your students for 2 hour lecture, I hope that one of my students would answer this question in behalf of me!! I believe that I should be all of the above at the same time, especially when it come to the entertainer part! I through jokes that are relevant to the class talk about movies that are relevant to the subject, and then return to main subject, I think this alteration between being serious and being funny would give the student a mind break
