Don't Show the Whole Gorilla 

In music, the Phrase "Don't show the whole gorilla" means to avoid giving full volume in any crescendos untill the song's climax, thus "hiding the gorilla". The phrase comes from king kong, in which the audience is teased and hinted at to what is behind the curtain when kong is captured.

Band Director:On this next run-through, use your phrasing and dynamics well, but Don't Show the Whole Gorilla untill measure 74.

Don't leave horsepower in the showroom 

A metaphorical rule to live by: don't make the mistake of choosing the cheaper option to save a buck in the short run, when you'll curse yourself later for not getting the better-grade product/service in the long run.

Eric: "What was I thinking buying that Porsche with the V-4 instead of the V-6 -- it handled like a Formula 1 car but is a total slug in a straight line!"
Tim: "Dude, you broke rule number 1 -- don't leave horsepower in the showroom."
And so --
Maddie: "This well Margarita sucks -- why didn't I get the Cadillac for two bucks more?"
Amy: "Exactly. Don't leave horsepower in the showroom, sweetie."
