Just a quick note today.
One of the most important aspects of a joke is: Surprise them! No predictable punchlines.
1. Mislead / misdirect them. One example follow:s
In the UK we’re on Red Alert: a terrapin has escaped from Chester Zoo. If you see the suspect, be careful, and if he pulls the pin out – Run!
The idea of this joke is to have 'em confused, wondering if you're talking about a terror subject or an amphibian, or, in the end, a hand grenade. The word "terrapin" is fabulous for this purpose, starting quite legitimately in a zoo and separating into two parts, a weapon and terror. There must be other zoo animals whose names could lend themselves to comment in some way on any subject, meaty or otherwise. Perhaps you could do some brainstorming? I might make this my next post.
2. Spend time boosting your creative thinking to such a degree that the ordinary man or woman simply can't keep up with you. "Creativity is simply linking the unlinkable." So, practise linking objects with concepts, ie a politician you don't admire with fruit, say a pineapple
3. Compare and Contrast: Find similarities and differences between two widely diiffering objects
4.. Try Edward de Bono's lateral thinking. method. It's fully described (price £1...92) in "50-Word MiniSagas: A Silver Bullet for Writing Success" at Amazon Kindle ASIN numberB00AOBNHNW, which is a highly useful book anyway. I should know, because I wrote it.
Use these methods and, whatever your starting point is, your creativity will grow, and with it, your natural gift for comedy.
