You must be a great teacher as per ur post here, You mentioned some great stuff that are really valuable.
I believe that comedy in the classroom is fine but not on a daily basis because the teacher may loose his value in the eyes of his students, and sometimes comedy in the classroom could make respect vanish between the teacher and students, in the contrary there are some teachers who use comedy as a main component in their teaching strategy,,so comedy is a double-edged sword and depends on the teacher to know himself very much before ending up with non-expected results.
Keep ut up for the good
