Humor is an essential part of spontaneity, an essential part of playfulness, an essential part of the creativity that we need to solve problems, no matter how ‘serious' they may be.
I’ve been doing improv comedy for the last twelve years. Over that time I’ve realized there are at least two types of laughter you hear from the audience. One is a response to something clever or smart, like ‘ha ha I see what you did there, very nice.’ It’s a shallow sort of laugh and one that comes mainly from the mind.
