“David is older now; he had heart surgery some time ago and sees both Jimmy Kimmel [of ABC’s “Jimmy Kimmel Live!”] as well as the more formidable Jimmy Fallon now gaining on him…” the insider told FOX411...

Probably the only time we will ever see the word "formidable" used in association with Jimmy Fallon. Frankly...I've seen inebriated homeless street performers with more talent.

I agree. It is simple demographics, the older stupid crowd goes to bed earlier and the idiot hipsters are the ones watching tv now and Letterman is a doofus.
