In Tom Robbins' Even Cowgirls Get The Blues, the narrator attempts to describe a Whooping Crane in 25 words or less. One attempt at the description reads Imagine Wilt Chamberlain in a red yarmulke and snowy feathers... The narrator cuts off the attempt with the explanation You're assuming that the reader knows who Wilt Chamberlain is. Many people don't follow basketball and wouldn't understand that Wilt signifies size and strength and arrogance made palatable by grace.
