The people at CBS and Late Show at David Letterman know that after Monday's blistering take on NBC, they could have some more fun tonight. Except now that Conan O'Brien announced today that he would not move The Tonight Show to 12:05 a.m., the balls are in NBC's court, and tonight's Tonight Show will be one to watch (they're all ones to watch, BTW). So CBS has put up these two clips from tonight's Late Show. The first has Letterman giving NBC an idea on how to replace "Big Jaw" Jay Leno at 10 p.m. with another Law & Order…Leno Victims Unit.

When Letterman gets to the desk tonight, it sounds like he is rehashing his advice from last night, only with updated information about the ongoing battle at NBC to reply to Conan's announcement this afternoon. Also, as Letterman tells Carson Daly, the difference between having a TV show at 1:35 a.m. and not having a show, isn't that much of a difference. Roll it!

The Hollywood Reporter also has gotten hold of quips from Letterman's monologue. "I just knocked off another competitor!"

UPDATED: Here is Letterman's Tuesday monologue!

In part two of his monologue, Letterman also gets in a dig on Leno regarding Simon Cowell's decision to leave American Idol. Then it's back to Sarah Palin jokes.
