According to Osho, don’t hunt jokes to fit talks; reverse it. Fall in love with a joke first, then let the right question or moment naturally appear. Perspective shapes relevance, so stay playful and receptive: life, or your audience, will provide the cue. Fit your talk to the living pulse of the joke, not vice versa.
Keep the jokes you truly enjoy, then wait for the right question or topic to appear and build your talk around that.
