A statement often screamed at American television audiences by silly-named men such as' Crazy Larry' or 'Crazy Eddie' during a local sales event. Everything must usually go when a store is undergoing liquidation or going out of business.

An example usually screamed in a fast talking "in your face" manner:
EVERYTHING MUST GO! Come on down to Crazy Larry's Bedding Barn and save big cause EVERYTHING MUST GO! We've got twin mattresses, queen-sized mattresses and king-sized mattresses at the lower prices around! We can't be beat! I've been slashing prices all over the store! Why? 'Cause I'm CRAZY! So come on down to Crazy Larry's 'cause EVERYTHING MUST GO!
