Michael Douglas stopped by David Letterman’s show last night, just three weeks after he learned that he had Stage-4 throat cancer. Looking healthy, the star of this month’s Wall Street sequel explained his diagnosis and prospects for recovery — about 80 percent. Letterman apologized for focusing so heavily on his guest’s vibrant appearance, “You look great and you don’t sound like you have throat cancer. Why is that?”

“Because I’m on stage,” replied the Oscar-winner, recognizing who and what he is.

Here’s to a speedy recovery and only good news for Douglas and his family.
