"Oh darling" said one to any of the other three (she wasn't too particular, having drunk several shots of Grippo polish with Monkey Grip chasers): "if only we could free ourselves from these canvas restraints we could embrace properly!"
"Steady on Eileen" said the other three all at the same time and in remarkable harmony: "We have a sneaking suspicion we may all be related!"
