I think there have always been funny women, from Carol Burnett to Joan Rivers. When the audience sees a woman, they innately know she's worked twice as hard to get there, she's had to prove that she can be the leader, first, and then be funny on top of it. She has to emit a confidence that she's in control.
How vain painting is-we admire the realistic depiction of objects which in their original state we don't admire at all.
