<passage>:
MONICA! The White House may have been in crisis all year, but the events were less the stuff of great drama than of a farcical musical comedy. Hey, wait a minute--let's put on a show! The time: November 1995. CLINTON CLINTON: OK, tell the ushers To take a few days off. Tell the maids and cooks and butlers Who will get the phones? CLINTON [speaking]                : We've got to make sure the Oval Office functions with efficiency. We can't afford the tiniest error. We'll bring in an intern, I assure you, Mr. President-- [Enter Betty Currie.] CURRIE: Mr. President? The intern is here. And she's brought you some pizza! [The lights go down. When they resume, the intern-- MONICA LEWINSKY --is talking on the phone to her good friend LINDA TRIPP .] LEWINSKY: Well, y'know, I'd seen him around, like, a lot. And I know he noticed me. So when they said they needed an intern to answer the phones, I said, "Hel-lo-o-o!" And then I had the idea to take him pizza! TRIPP: And then what happened? "What Went On" (upbeat) LEWINSKY: Then I led him on. I showed him my thong, I let him take a long and ling'ring look. His hands roved freely 'neath my blouse, I reached into the presidential trousers, And he got a phone call from a member of the House. Though what the congressman heard was "Please, please, please, please, please!" But then we didn't go on! TRIPP: You didn't go on? LEWINSKY: No, he stopped me when he seemed upon the cusp. TRIPP: So you didn't go on? LEWINSKY: No, we didn't go on. He said he wasn't sure if I was someone he Could [The lights fade as the girlfriends engage in cross talk.] TRIPP: Trust? LEWINSKY: That's why we didn't go on. TRIPP: That's so weird! What did he think? That you'd go blabbin' this to the whole world? TRIPP: It's just my gum. LEWINSKY: Oh--OK! [As the relationship between Clinton and Monica continues, some members of the White House staff become worried about the prudence of continuing the relationship with so much potential for scandal. This song is a conversation between Betty Currie, who, though worried, still thinks Monica is a good person, and the rather stonier EVELYN LIEBERMAN .] "Time to Go" CURRIE: They go back there, It's just what she picks to drink. Betty, it's Lewinsky's time to go. CURRIE: She brings him LIEBERMAN: It's not the junk I mind as much As her up real close and personal touch. I tell ya, it's Miss Monica's time to go. CURRIE: She never comes When he's really busy. LIEBERMAN: Good idea--don't wait! LIEBERMAN: Let's get Clinton's head on straight! LIEBERMAN: "Hallelujah, He Is Risen" Shouldn't inspire thoughts so sizzlin'. Yes, it's really time for Monica to go. [Times passes. Monica moves to the Pentagon, but the relationship intermittently continues. Meanwhile, Paula Jones sues the president for sexual harassment, and it seems clear that before long, Clinton will have to testify under oath. Two close observers of those developments are old friends Linda Tripp and LUCIENNE GOLDBERG , who is friendly with lawyers for Jones and lawyers in the office of Independent Counsel KENNETH STARR . One day, Tripp and Goldberg talk on the phone.] "Talk, Talk, Chat, Chat" (sprightly) GOLDBERG and TRIPP: Talk, talk, Chat, chat, Two old girlfriends dish the latest dirt. GOLDBERG: I got tickets To the opera, Bloomie's says I've got $40 due, That's it for me, Now tell me what's up with you. TRIPP: My friend Monica? From the White House? I'm pretty sure what she's saying here is true. It seems this Monica chick Has been sucking the president's-- GOLDBERG: Oh that's sick! TRIPP: And the two of them are going to lie about it, Too. GOLDBERG: Back up, Linda, Did I hear you rightly? Clinton got into an intern's pants? God, this news is manna, Linda! At last our cause will finally have it's chance! He'll spin the story, he'll turn the tables-- GOLDBERG: Unless you get that airhead down on tape. TRIPP: What? GOLDBERG: Unless you get that silly, vapid, trampy time bomb Down on tape. TRIPP: There's a dress ... GOLDBERG: Hold on, let me call Sparky. [Independent Counsel Starr uses Tripp to detain Monica. A few days later, the news breaks. On the advice of his pal Harry Thomason, Clinton flat-out lies to his wife, to his loyalists, and to the public about the relationship.] "I Never Have" (performance should build in tempo and intensity) CLINTON: You know I'd like to answer questions, An act my lawyers won't allow. I'll give you more not less, sooner not later, Her head's full of who knows what. But I never had sex with that woman I never had sex with that n-- Starr has spent $40 million, There's desperation on his face. All he's got is some recordings Made by a vengeful snitch. I never had sex with that woman I never had sex with that Girl. [Months of investigation, legal wrangling, and public relations campaigning follow. Starr's tactics come under heavy fire, to which he responds.] "Crossing the Line" STARR: It's true Monica asked to lawyer up, Which Bittman put the lid on. And I felt bad about her mommy's grilling I'd be a nitwit not to bend a bit When the president crosses the line. The talking heads are accusing me Of laying a perjury trap. I've had sex. It's fine. But lying about it gets my blood up And the president's crossed the line. I crossed the line. Tell Steve Brill I'll leak at will When the president crosses the line. [After months of denials and futile delays, Clinton finally testifies before the Starr grand jury and argues that, technically, he didn't lie.] "Testimony" (snappy) CLINTON: Depends what the definition of "is" is, Before you reach conclusions, read your text. [Afterward, he speaks to the nation, admits doing wrong, and apologizes, though grudgingly.] CLINTON: Inappropriate was the nature of our actions, And believe me I regret the whole damn thing, But inappropriate are all these personal questions, The country doesn't need to know these things. [Clinton's enemies reject his apology, and soon the House of Representatives begins the long process of impeachment. NEWT GINGRICH here discloses his approach.] STARR: The election was held and the people have spoken, I can't believe what they had to say. I had Clinton boxed into a corner Looks like he's going to get away. I spent four years and 40 million That's a lot of time and loot. I made Clinton look ridiculous, LEWINSKY: The election was held and the people have spoken, I can't believe what they had to say. My boyfriend is still in office Kenneth Starr should go away.
