From the Daily Show with Jon Stewart (click here for the video):
(Jon Stewart talking to Senior Correspondent Ed Helms regarding Hurricane Katrina)
Stewart: In your judgment, is this the worst crisis this administration has faced?
Helms: Well Jon, as you know, administration fiascos are named alphabetically. As you can see, Katrina is their 11th out of what could be 26 colossal failures. I don't know if you see those last two on the list there, Jon, but by the time "Zero People Left on Earth" rolls along, that "Yam Shortage" will be long forgotten.
