this isn't cheeky, and Buddhist stories seem unlikely to have made their way into English proverbial expressions, but...
The Buddha, it is said, used to delight in relating the following parable:
A King once, for his amusement, invited nine blind beggars to his palace. Then he had an elephant brought in, and having each man examine one part of the elephant, ordered them to tell them what an elephant was.
One felt the trunk, and said "it is a palm-tree". One felt the head, and said "it is a big cooking-pot". One felt the tusk, and said "it is a plough-share". One felt the ear, and said "it is a winnowing basket". One felt the belly, and said "it is a grain silo". One felt the leg, and said "it is a pillar". One felt the tail, and said "it is a snake". One felt the end of the tail, and said "it is a big brush". And one felt the back and said "it is a quern".
Hear the other's outlandish claims, each blind man became enraged and tried to shout the other's falsehoods down, until at last they came to blows, which greatly amused the king.
"Just so", says the Buddha, "are scholars who, groping in the dark about this world, claim it is this way or that way, being noisy and quarrelsome about it".
