From memory,
that April Fool inspired me to writing an omake where Louise's Familiar was a (generously hovering on anti-gravs) CSU* Bolo ... Arguably... a bit more up-market than a Super Shotgun (or even a (basic) Varga),,,
"So, 'Mr. Retief' *, you are an... avatar of my Familiar? Which is now... At a safe distance?"
"I'm more... a social interaction... subsystem. Something of a... diplomat, I'd hope. 'Living flesh over a flint-steel endoskeleton', to misquote someone. Lets me taste the wine... dance with the pretty ladies."
* suspicious look *
"Call me 'Jame'."
*bows and brushes lips just over back of hand *
* honest this isn't a blush *
* CSU - 'Continental Siege Unit', for when a 'Planetary Siege Unit' would be excessive... Unit RTF of the Dinochrome Brigade is... a little unusual, in that they are skilled in diplomatic warfare, sorry, 'engagements'...
*
Jame Retief - nuff said

(Last seen inspecting the Diplomatic Expenses Voucher Files...)
((Just to be clear, Keith Laumer was the author of both the 'Bolo' and the 'Retief' stories. Was, BTW, a professional diplomat.))
