Gaping for gudgeons. Looking out for things extremely
improbable. As a gudgeon is a bait to deceive fish, it means a lie, a deception.
To swallow a gudgeon.
To be bamboozled with a most palpable lie, as silly fish are caught
by gudgeons. (French, goujon,
whence the phrase faire avaler
Make fools believe in their foreseeing
Of things before they are in being,
To swallow gudgeons ere they're catched,
And count their chickens ere they're hatched.
Butler: Hudibras, ii. 3.
