The old shot-too-soon trick. Over half a century ago, KVI radio, Seattle, produced a tongue-in-cheek superhero radio play called Superpickle. One scene cracked me up at the time. Our hero has overcome a stooge who knows WHODUNNIT.
HERO: All right, now tell me--who was it?
STOOGE: It was...it was... (PAUSES FOR A BEAT)
HERO: Come on, speak up! Who was it?!
STOOGE: it was...(LONG PAUSE, THEN HE SHOUTS OFF-MIKE) Whaddaya waitin' for?! It was...
SOUND: PISTOL SHOT OFF
STOOGE: Aggh! (BODY FALLS)
HERO: He's dead!
