Character Dossier: Gag Halfrunt

"'... We asked his private brain-case specialist, Gag Halfrunt . . .' The music swirled and dived for a moment. Another voice broke in, presumably Halfrunt. He said: 'Vell, Zaphod's just zis guy, you know?' but got no further because an electric pencil flew across the cabin through the radio's on/off sensitive airspace."

Gag Halfrunt is a prominent galactic psychiatrist and the private brain-case specialist to Galactic President Zaphod Beeblebrox.
The Sub-Etha Media Interview
Following Zaphod Beeblebrox's sensational theft of the Heart of Gold from Damogran, sub-etha news networks broadcast round-the-clock updates to all intelligent life forms across the Galaxy:
- The Question on Everyone's Lips: Media commentators eagerly asked whether "the Big Z had finally flipped."
- The Clinical Diagnosis: Asked for professional psychiatric insight into the runaway President, Halfrunt offered his immortal assessment: "Vell, Zaphod's just zis guy, you know?"
- Abrupt Disconnection: Before Halfrunt could elaborate further on Zaphod's psychological state or his extra head and arm, Trillian silenced the broadcast by hurling an electric pencil across the cabin through the radio's touch-free airspace.
