I know that this is too late for anyone to catch (I didn't get it on tape either), but last night (1/28) on Leno, after the monologue, Leno turned to Edd Hall (the announcer) who wasn't paying attention to anything. He was reading the Rolling Stones magazine with SP on the cover.
Here's a transcript, best that I can remember:
Leno: Edd? Edd! Are you paying attention?
Edd: Oh, is it time to start the show?
Leno: Edd, we just finished the monologue.
Edd: Oh, Jay, I thought that I'd pass the time by reading this
magazine. Look! It's those South Park kids in it! 'Oh my God, they
killed Kenny!' Those Bastards!
<Crowd laughs>
Leno: Where did you get that?
Edd: But the best part is when the rats start eating him!
<Crowd laughs again>
Leno: I knwo about South Park, but where did you get that magazine?
Edd: Oh, I got it out of your mailbox before the show.
Leno: You did what? Edd, that a fenoly!
Edd: So? What are you going to do, get Kenneth Starr to prosecute?
Leno: Go put that back right now! <Edd leaves> I hate to treat him like a
child, but he can be so immature sometimes!
<Edd walks by a ladder where two repairmen are trying to place a tv set
in its proper place. Edd, still reading the magazine is, is oblivious to
them.>
RM 1: OK, no move it a little to the left. Now to the right.
RM 2: Like that?
RM 1: Yeah, that looks perfect, now just push it back.
<Edd contines walking while reading, and stops beneath the ladder>
RM 1: OK, hey! Wait!
RM 2: LOOKOUT!
<TV falls on Edd, killing him.>
RM 1: <Looking terrified and disgusted> Oh, my God! You killed Edd!
You bastard!
RM 2: Let's get outta here!
<RM 1 and RM 2 leave. Edd lays on the floor, his head inside the TV. A
huge lifesize rat comes and starts nibbling on Edd. Cut back to Jay>Eric Bycer, Jedi Knight I'm surprised that no one else has posted that.
