"So as a woman on the box, you can either be funny, or sexy, but not both, right?"As evidence to the contrary I would beg to offer Julia Louis Dreyfus, who played Elaine in "Seinfeld". As actresses go she's pretty without being va-va-voom - but that doesn't matter. The charisma comes off her in waves and with it comes the quality that so often follows. I could watch her for days.
The show exploits it brilliantly because every now and then she does something to make the three men in the cast stop treating her like a friend. Believe me, it doesn't take much.
