      Monkeys are very similar to us in many ways. Most have ten fingers and ten toes, and brains

much like ours. In fact, Charles Darwin's theory of evolution says that monkeys and humans share

a common ancestor. We enjoy watching them because they often act like us, and we also love to

use many expressions about monkeys in almost every language This is why many monkey expressions

are about tricky people or playful acts.

      Monkeyshine is one of these expressions to show tricks or foolish acts. The meaning is clear if

you have ever watched a group of monkeys playfully chasing each other:pulling tails, stealing food,

doing tricks.

Monkeying around with something means that you do not know what you are doing. When you feel

like doing something but have no firm idea of what to do, you are monkeying around. It is just a way

report that there is monkey business involved in building the new airport, with some officials getting

secret payments from builders.

     Monkey suits are common names for clothes or uniforms soldiers wear. In earlier years in many

American cities, you would find men playing musical hand organs on the street. Dancing to the music

uniform. So, people began to call a military uniform a monkey suit.
