El Organillero y su Mono Silvio.
"I don't give a monkey". En Inglaterra: "Me importa un carajo"
"I don't give a monkey":
-It is a wholly impolite phrase, referring to the fact that monkeys (probably apes, actually) at the zoo masturbate freely and frequently, so that the action has no value. "I don't give a monkey's toss" has been shortened to "I don't give a monkey's" or "I don't give a toss". The alternative version was "a tinker's cuss". "I'll be a monkey's uncle" was an expression of surprise derived from the early arguments about evolution.-
