As a symbol monkeys can represent a number of things. It can be helpful to consider colloquialisms such as "monkey business" which might indicate someone is being foolish. Monkeys also tend to imitate what they see which could related to mockery (also a possible play on words here). If you make a monkey of someone it means that you make them look foolish. On a more positive note, monkeys tend to be rather intelligent animals and can related to the idea of being able to comprehend more than might otherwise be expected from outward appearances.
