John,

I might be a TV-show host known for jokes and pranks, but a few years ago I did something that's usually not a great sign for a comedian: I made America cry.

Yes, you read that right. I shared the emotional experience of watching my newborn son being diagnosed with a life-threatening heart defect—and ultimately being saved by the world-renowned surgeons and caregivers at Children's Hospital Los Angeles.

It's not just my son Billy's life these heroes have saved. Children's Hospital Los Angeles provides care for 1 out of every 5 children in Los Angeles, so chances are you or someone you know has been helped by this great hospital.

That's why I'm teaming up with Children's Hospital Los Angeles to raise $300,000 by midnight, Dec. 31. Right now, every gift to the Children's Fund will be matched and will go THREE times as far for sick kids. Please, John, make your tax-deductible year-end gift before this crucial deadline.

No parent should ever have to decide if they can afford to save their child's life. And at Children's Hospital Los Angeles, they never will. As a nonprofit hospital, the experts here care for Southern California's most vulnerable kids, never turning away a child because of a family's financial situation.

Children's Hospital Los Angeles needs your support to do more of this important work.

I hope you'll take advantage of this special triple-match opportunity.

Your year-end gift of $10 or more will go three times as far, but only until Friday—so please don't wait another moment to give.

Now at 5 years old, Billy is silly, energetic and the best little pal I could ever ask for. That's all thanks to the incredible doctors and nurses at Children's Hospital Los Angeles.

Today, you can help make more stories like Billy's possible with your tax-deductible gift.

Thanks for stepping up when it counts.
