Just in from CBS:

"Following its successful first 'Impressionist Week' last fall, Late Show with David Letterman will once again showcase some of the best impressionists in entertainment when it presents 'Impressionist Week 2,' Monday, April 30, through Friday, May 4."

The lineup looks like this:

Monday: Rob Magnotti
Tuesday: John Byner
Wednesday: Mike MacRae
Thursday: Joe Piscopo

I've plugged my own "Jimmy Stewart" here before, but have I told you about my "Rocky Balboa"? It'll knock ya to tomorrow, I tell ya.
