Motivation and ritalin.

Well, ask and ye shall receive, sort of (see post below). Robin Williams, Bill Maher, Ellen Page, Shooter Jennings and cast members from “Young Frankenstein” are among the guests David Letterman will have this week when his first original segs in more than two months air on CBS, starting Wednesday. (Note the parenthetical emphasis that these are NEW, ORIGINAL broadcasts at long last. Usually those block letters denote repeats and original airdates.)

The guest list is interesting, but it’s the monologue and scripted (whoo-hoo!) bits on these shows that we’ll be most interested in seeing.

Here’s the listings rundown CBS issued this morning:

*Wednesday, Jan. 2                           Actor Robin Williams; musical guest Shooter Jennings  (NEW, ORIGINAL BROADCAST)

*Thursday, Jan. 3                              Comedian/talk show host Bill Maher; actress Ellen Page; a performance from the Broadway musical “Young Frankenstein” (NEW, ORIGINAL BROADCAST)

*Friday, Jan. 4                                   Real estate mogul Donald Trump; musical guest Lupe Fiasco (NEW, ORIGINAL BROADCAST)
