: There is a sarcastic expression, now a bit dated, used like this: "his analysis had all the depth of a saltine cracker". This is a U.S. expression. I wonder what similar phrases have developed in other parts of the English speaking world, and also what more recent ones may have developed in America. Thanks! - Patty
In the UK, we occasionally use "sharp as a rubber mallet", when describing something or someone mind-bogglingly unperceptive.
