Yes, David Letterman can afford his own flowers, and yes he can easily buy for himself anything we'd care to send him.
"Oh, look. DU bought me a Toyota Prius. I'll just park it in the garage next to my private Space Shuttle."
I think it's important to contact Mr. Letterman, to express our gratitude.
But I also think it carries more weight if showing your thanks also involves some kind of sacrifice from yourself.
That's why I think we should donate to Media Matters in Mr. Letterman's honor:
mm-donations@mediamatters.org and someone will contact you.
In the "Comments" field, write that your donation is in honor of David Letterman.
And then email Mr. Letterman to let him know what you did.
YES, I want to help correct conservative misinformation in the media by making a fully tax deductible donation to Media Matters for America
