For a workable sense of humor counts: the guts to practice. The next thing to have is a good memory where all the jokes ever heard or told are stored. Then, you may need some creativity to adjust old ones to recycle them. And I always laugh about my own jokes that none go to waste.
When one of my kids was a young teenager, a good friend asked: What do you hate in sweets. Bug-eyed, he answered: Nothing! To which his friend replied coolly: When they finish.
I made countless variations to this, both in the negative and in the positive. I share to inspire. Feel free to copy.
● At the bus stop (endlessly): What do you love about standing at the bus stop? When the bus arrives.
● What do you love about war? When it’s over.
● What do you hate about your friends? When you miss them.
● What do you hate about nice weather? That it passes.
● What do you like about Trump? Can I get back to you on that one?
Make sure you fine-tune the joke to your audience.
And, you don’t have to make everyone happy, be pizza.
