Below is a quote from one of the several books I've read which I think might help you make others around you happy.

"Clowns are people with more heart than comics. Clowns make fool of themselves whereas comics make fool of others. To make people laugh is the greatest thing a clown can achieve. It means, for a moment, they leave their worries behind. For a moment, they are liberated and happy. You are a success if you can do that for people" - Anon
