Shakespeare seems to like writing ladies disguised as men, since he uses it in a couple of plays. Of course, most actors were men anyway, and frequently played the women's parts.

The traditional love triangle is upgraded to a love trapezoid, which makes for all sorts of hilarity! I love it, of course! Especially the bits where Viola and Sebastian (identical twins) are being mistaken for each other by every one. ha ha! That made me laugh.

Spoiler Alert:
At the end when the Duke proposes to Viola, after finding out that she's actually a woman, it struck me that he repeats twice that she should change into her "woman's weeds". Maybe he wanted to see how she would look in a skirt before he would commit himself to marrying her? hah a! Maybe she'd make a good-looking man but an ugly woman. ha ha! He wanted to make sure he liked her looks before he marries her. :) Ah, the wily old duke.
