Glory
Well, as far as glory is concerned, there's plenty to go around for clowns. You could become nominated Clown of the Year by the World Clown Association, or simply bask in the sound of a child's laughter—something many clowns argue is a reward in and of itself.
You'll have the satisfaction of making people happy and you'll earn a living doing it. You can bring laughter to the lives of sick children, elderly folks in old age homes, or just your average Joe having a bad day. Your karma will be excellent.
