     Monkeys are very similar to us in many ways. We enjoy watching them because they often act like

us. In fact, scientists say monkeys and humans share a common ancestor.

     Monkeys make us smile, too, because they are creatures full of playful tricks. This is why many

monkey expressions are about tricky people or playful acts. One of these expressions is monkeyshines,

meaning tricks or foolish acts. So, when a teacher says to a group of students: "Stop those monkeyshines

right now!", you know that the kids are playing, instead of studying.

     You might hear that same teacher warn a student not to monkey around with a valuable piece of

equipment. You monkey around with something when you are touching or playing with something you

should leave alone. Also, you can monkey around when you feel like doing something, but have no firm

idea of what to do.

     Monkey business usually means secret, maybe illegal, activities. A news report may say there is

monkey business involved in building the new airport, with some officials getting secret payments from

builders.

     You may make a monkey out of someone when you make that person look foolish. Some people

make a monkey out of themselves by acting foolish or silly.

     If one monkey has fun, imagine how much fun a barrel of monkeys can have. If your friend says he

had more fun than a barrel of monkeys at your party, you know that he had a really good time.

     Monkey suits are common names for clothes or uniforms soldiers wear. In earlier years, performing

monkeys' tight-fitting, colorful jacket looked similar to a militaryuniform. So, people began to call a

military uniform a monkey suit.
