Boyaux Boyaux!

As In "Boy Oh Boy".  At Least I Think That's How It's Pronounced
And what is it?  French idiom, actually.  Literally taken it means "guts" and actually refers to trenches, a.k.a. saps, in the sense that when in a trench one is in the very bowels of the earth.  Or it's guts.
     'Fascinating!' I can hear you say.  'An inconsequential yet illuminating fact brought to the attention of a wider public, thus underlining the didactic mission of BOOJUM!'
     You do talk verbose, don't you?

That chap Andy Robertshaw in a boyaux

     What you left out was speculation on why this word had come up; because it occurs in "The History of the 51st Highland Division", although today - being in a merciful mood - I shall not punish you with a 150-word screed about indexing.  I shall however mention -

The Barratt Forcing Jack - Today's Mad Science!
I'm afraid you'll have to do with a modern pipe pusher, or hydraulic forcing jack, as I simply cannot find any pictures of the Barratt version; I guess that it's a very obscure invention from a century ago, that was dismally unsuccessful, and is not mourned at all.
     Allow me:

A pipe pusher pushing pipe.*

     This device, still widely used today, uses hydraulic pressure to push a pipe through the ground.  A cheaper and more convenient method than digging a trench and laying the pipe in the boyaux created.
     The BFJ was intended to drive a pipe under No Man's Land several hundred yards long.  This would then be filled with ammonal, an explosive, and detonated.  Net result - instant trench.
     That was the theory.  In fact the giant midden that was No Man's Land would have all sorts of subterranean obstructions; tree roots, buried timber, rubble, bodies, unexploded shells - the list goes on.  When the pipe encountered an obstruction, which it very often did, it would divert in a wildly different direction from the one intended and indeed on several occasions came right back at the British lines.

Jack and pipe.  Close enough

Bemused By BMEWS
The previously-threatened article.     The acronym for "Ballistic Missile Warning System" - and yes we are back into the territory of the Big Bang Bombs, although this is defensive technology.
     Theoretically, a BMEWS would give from between 15 to 25 minutes warning of an incoming ICBM** strike.  The ones at Thule in Greenland or Fylingdales Moor in Yorkshire had Partial Parabolic Reflectors, which would pick up the flight of an ICBM over the horizon and work out an approximate track.  A second Parabolic Reflector under a radome would work out the fine tracking and attempt to give a definitive impart point.

It's obvious why they were called "Golfballs"

     I say "attempt" because MIRVing*** missiles meant that up to 14 separate warheads might be directed at different targets, and you'd only know which after the missile "bus" separated from the missile body.  By then your warning time is radically reduced.
     What might be called the "Anti-missile missile missile" also makes impact prediction different.  These are MARV^s, and they have control surfaces that allow them to glide after release, extending their range considerably.  When over target they suddenly go into a terminal dive, making it very hard for anti-missile missiles to intercept.
     Nuclear weapons theory: fascinating but very very worrying -

 - so here's a pic of baby duck-billed platypi instead.

Shakeshaft
Let us move onto something a little lighter.  Only a little, Shakespeare is littered with death and murder and manifestations of evil.
     Anyway, take that! for making O and A Level English a chore, you Stratford swine!

"All the world's a stage,

And all the men and women merely players.

The best fictional detective of this age -

Lord Peter Wimsey, by Dorothy Sayers"

Never a truer word put into print.  What else can we inflict upon matey?

"Out vile jelly

You're so smelly!"

Anything else?  I did wonder about Aeriel's dad:

"Full fathom five thy father lies

Scuba-diving of the coast of Belize"

     Ha ha!
     Well it amuses me.

"Pitch Perfect 2"
Eh what Say what?  I wasn't even aware that there was a "Pitch Perfect 1".
     Another victim of the BOOJUM! school of film review!

A dangerous sport - pitch-provoking

          This has got to be one of the most boring films ever made.  Whether the visual torture lasts 90 minutes or 120 is a bit irrelevant as your mind would melt after merely 5.  I ask you, who would want to watch a film that consists of boat-sealant setting?  
     Pitch Perfect 2 - a film so dull it make watching paint dry look like a dangerous spectator sport.

My Time At MI5
Let me recount how a typical day of mine went:

"6:15  Wake up next to the Countess, slip silently out of the room leaving her a note about how I knew that she was a hostile agent, and that she knew I knew, and that I knew she knew I knew, at which there was no more space left on the Post-It.
     Exit via lobby, only pausing to have brief bout of unarmed combat with a Russian assassin, disabled him with subclavian nerve pinch; he might have been Ukranian or Polish, his accent was a bit hard to tell after karate chop to throat.
     Slid into the De Tomasso Pantera in the car park, had to dodge a couple of motorbikes carrying passengers with machine guns, threw them off by driving the wrong way up the M25.  Had to engage stealth shield to prevent apprehension by police.
     8:30 Arrived at office, flirted with receptionist - he finds it flattering - and handed over my Desert Eagle for safe keeping.  Then to briefing by M.
     11:15 Refresher training:  How To Quip Tellingly When Your Life Is In Mild/Severe/Terminal Peril
     12:30  Lunch at the Special Forces Club -"

Our discreet undercover HQ
Really, all that's missing is a giant neon sign saying "SPIES HERE"

     And then the alarm clock goes off and I wake up.  Bed next to me is occupied by the cat, who somehow snuck into the room again.  I struggle with crowds on the Tube - that's as fatal as it gets - and the humourless Receptionists would report you to your Section Head if you so much as crack a joke.  I have only ever seem M on television, but I got a dirty look from Q once^^.
