Davis:  Proper billy - club use Karen , that 's the secret . I find it helps if you give your billy - club a name . You know what I call mine ?
Karen Pelly: Billy ?
Davis: Anyways , a billy - club is a cop 's best friend .
Karen Pelly: I thought you said a gun was a cop 's best friend .
Davis: Well , a gun is more like a cop 's lover . There 's some things you tell your gun that you 'd never tell a lover . And sometimes your lover and your best friend do n't get along . Or maybe you go out with _ one _ and the other gets mad at you 'cause you did n't go out with it !
Karen Pelly: You 're divorced right ?
