One of the kiwi ones: the last verse of 'The ballad of Q for Queenie', a 490 (NZ) sqn Sunderland that had "more than a few" engine problems, usually at the worst possible moment...
Q for Queenie broad and beamy.
Pregnant cow, contrary witch,
Ground crews' headache,
Aircrews' heartache,
Pull the plug out. Sink the b!tch.
(Penned "with some feeling" by her tail gunner, Flt.Sgt. Maurice (Robbie) Robson...)
