Public Speaking Course:
Proverb Fortune Cookie Humor
(You will need to make sure this is politically correct for your particular audience.)
Here is a good article from my public speaking course. A cute way to throw in a diversion to an otherwise boring presentation is by attributing a saying to an ancient Chinese philosopher. Since these sayings are not attributed to anyone in particular, feel free to change or update them to fit your situation and to add to their humor.
Original: You cannot prevent the birds of sadness from flying over
your head, but you can prevent them from nesting in your hair.
Original: He who walk on eggs should tread lightly.
Original: People who live in glass houses should not throw stones.
The contrast of the update to the original provides the humor and is practiced in your public speaking course.
