Why?

Questions from last week's TV:

1. Is Dwight Schrute that evil that he would kill Angela's cat?
2. Why is it that the men whom Izzie grows fond of die? Is George gonna croak next?
3. Why does Lexie continue to try to ask Meredith questions? Why is she so ditzy?
4. Why are there so many interns on Grey's Anatomy? They look so obviously like extras.
5. How did some of the models (like Jenah )on America's Next Top Model make it on their show? Get a professional makeup artist on me and an art director directing my shoots, and I can be just as FIERCE.
