Reminds me of:
Prisoner: There's a message through the grapevine, Johnny.
Johnny Dangerously: Yeah? What is it?
Prisoner: Johnny and the Mothers are playing "Stompin' at the Savoy" in Vermont tonight.
Johnny Dangerously: Vermin's going to kill my brother at the Savoy theater tonight.
Prisoner: I didn't say that.
Johnny Dangerously: No, but I know this grapevine.
