“Analyzing humor is like dissecting a frog. Few people are interested and the frog dies of it.” E. B. White
It’s painful to watch someone TRY to be funny.
The secret is in the word itself.
Just be fun. Don’t worry with the ny part.
Tell your embarrassing moments – who doesn’t love to hear about humiliation.
Share what makes you smile.
If you’re friends laugh at/with you regularly then take that same spirit into other situations or the stage.
If they don’t, then forget being someone you’re not and just tell jokes. If the jokes don’t work become an accountant.
Regardless, have fun. Smile more. Share more. There are plenty of grumpy people one more isn’t needed.
