A lot of great entries on this one. I could have listed ten runners up as easily as three, but I've cut them down to these, in no particular order:
Treadigraph -- We must look a right pair of Panzers with these brollies...
Wensleydale -- Hitler's Winter Offensive in December 1944: "Wacht am Rain"
Dan Gerous -- "Oleg, why are we going into battle with this captured stuff from WWII"?
"It's simple Yuri, they can't blow the turrets off these"!
First place goes to the one that made me laugh the most, and I'm a sucker for goofy puns. So Confusious takes it with:
I yelled "up persiscopes" then up popped a 'pair o' dopes'.
The trophy will be on its way as soon as the weather breaks.
