As mad as a box of frogs

The title of this post is an example of a simile, a figure of speech that expresses a resemblance between things of different kinds, and which usually starts with as or like. Some examples of well know similes include, as slippery as an eel, as busy as a bee, as thick as two short planks, and as easy as falling off a log.

The word simile comes from the Latin simile (something similiar) from similis (like).

Here are a few less well know / freshly minted ones:

as reliable as a fox wearing a cravat
as dextrous as an octopus using seven pairs of scissors
as easy as herding cats
as spotty as a teenage leopard
as doomed to failure as a bouncy castle birthday party for hedgehogs
like a duck to custard
like lambs to the mint sauce
as big as a very big thing
as happy as a Frenchman who’s invented a pair of self-removing trousers (from Black Adder)

Have you spotted or coined any interesting or bizarre similes recently?
