Grey's Anatomy, Season 7

Meredith:
[voiceover] We doctors, take pride in the fact that we can basically sleep standing up. Anytime, anywhere. But it's a false pride because the truth is, after about 20 hours without sleep, you might as well just come to work drunk, doctor, or not. So, it's no wonder that fatal medical errors increase at night. When we doctors are, proudly, sleeping on our feet. Recently, our communal pride has been shattered, and our egos have been wounded by new laws that require that we sleep all day before we work all night. We're not happy about it. But as someone who may one day need medical care, you really should be.
