Bob Saget’s good deed.

‘Cool Comedy” is an event that Bob Saget began years ago in honor of his beloved late sister, who’d died of Scleroderma.

He vowed to find a cure.

In a few years’ time, he has raised thousands of dollars… and advanced medicine.

The event is always star-studded, and Bob handles host duties with poise — an an occasional, brilliant zinger.

I wrote him a note after this year’s party to let him know (a) how much I enjoyed it, and (b) what a good brother he has been, and how proud his sister must be.
