By my much loved and very much missed Lithuanian Humourist, late but still alive for me...
Tankos tai ne tankų patelės, o tokie japoniški eilėraščiai.
Jurgis Gimberis
The EN for the above is "Tanka is not a female tank but a certain Japanese poem"; and I suppose I`d better add RU, as well; for a variety of reasons, but mainly because the RU version sounds even better than the source maxim. It even kinda rhymes!
Танка - то не самка танка, а такой японский стих!
The author also presents extended (explanatory):
Tankos tai tik poezija, o ne tankai. Tai nepavojinga. Nebent psichiškai... (Tankas are just poetry, not tanks. Not dangerous. Except perhaps mentally...)
I do miss Jurgis Gimberis! A pity his very best witticisms are totally untranslatable...
