It should come as no surprise that the entertainment world has spawned an exceptional number of idioms and expressions that we use in our daily lives. After all, artists are an endless source of creative ideas. Phrases from the radio, the circus, theater, cinema, and television have remained in the memory of English speakers expanding our vocabulary to no end. In this article, we’ll uncover the origin of 10 expressions that showbiz has gifted us for our sole entertainment. Join us!
Break a leg

This is probably the most popular idiom derived from the performing arts. To hope somebody breaks a leg may sound negative but in fact means you want them to have good luck, usually when it refers to stage actors or musicians. Some historians believe the expression originates from the assassination of President Abraham Lincoln who was shot at Ford’s Theater in 1865. His murderer, a renowned Shakespearean actor called John Wilkes Booth, is said to have broken his leg while trying to escape.
The claim that the saying arose as a form of black humor in relation to this event is probably wrong. In fact, the phrase was in use centuries before that. In theater, actors measured the success of a performance by the number of times an audience called them back for applause. Each time the curtain was reopened they bowed, and the more often that happened the greater the chance of "breaking a leg".
Blonde bombshell

Over the years Hollywood has given us a good sample of blonde bombshells: Marilyn Monroe, Mae West, Jayne Mansfield, Marlene Dietrich, just to name a few. But do you know where this expression originated? Nowadays, a blonde bombshell is an expression used to describe any attractive blonde lady, usually a singer or film star.
However, the original blonde bombshell was American actress Jean Harlow, known for her portrayal of "bad girl" characters and star of the 1933 film Bombshell. When the film was released in the UK, producers changed its title to Blonde Bombshell as they worried it might be perceived as a war film. The expression immediately became popular on both sides of the pond.
Old chestnut

An old chestnut usually refers to a stale joke or story, something that has been repeated too many times. According to the Oxford English Dictionary, the origin of the saying dates back to an 1816 play called The Broken Sword. One of the characters often repeats the same joke about a cork tree, with slight variations each time. Another character, Pablo, interrupts and says, "It’s a chestnut. I have heard you tell the joke 27 times and it’s a chestnut."
But the story doesn’t end there. Years later, an American actor called William Warren, who had played the part of Pablo in the melodrama, was at a society event when another guest began to recite an old, worn-out joke. Warren, bored to tears, interrupted and said, "It’s an old chestnut, that’s what it is", much to the amusement of everybody there. News of the incident spread amongst their acquaintances and beyond and that is how the expression is still alive and kicking to this day.
Face the music

Face the music is a popular idiom used to express that we have to accept responsibility and be confronted with the unpleasant consequences of our actions. It has two possible origins. The first one has to do with theater and refers to nervous actors on opening nights when they have to go out on stage and quite literally "face the music", as the orchestra pit sits directly in front of them.
The second explanation, on the other hand, is related to the military. It suggests that a dishonorable discharge results in the disgraced soldier being marched off barracks to the sound of drummers playing, in which case he too has to "face the music".
As fit as a fiddle

As fit as a fiddle is used to indicate a person is in very good health. A fiddle is a stringed musical instrument, a forerunner of the violin. As you can imagine, this idiom has its origins in music, but also in theater.
The earliest reference to the expression has been traced to William Haughton's 1597 stage play Englishmen for My Money: "This is excellent, i’faith; as fit as a fiddle." Back in the days of medieval court, the word fiddle applied not only to the instrument but also to the fiddler and, by extension, to an entertainer. It is possible, therefore, that the phrase describes the fiddler, a vivacious character who made the company merry and played his instrument throughout the crowds, which makes a lot more sense.
Jumping the shark

Jumping the shark is a phrase used in showbiz to describe a good television show that is experiencing a decline in quality and has reached a point at which flashy scenes are included just for show. This has been the case with many classic comedies, which ran for too many seasons and at some point started repeating themselves.
Happy Days was one of the greatest sitcoms of the 1970s. Americans across the country were captivated by the adventures of Richie Cunningham and his family until the writing became tired and viewers started to switch off. The final straw was a scene in which The Fonz —Henry Winkler— is waterskiing in his leather jacket and boots and literally jumps over a shark. For many critics that scene marked the end of the show and the beginning of a long-run expression we still use today.
Play it by ear

According to Cambridge Dictionary, to play it by ear means "to decide how to deal with a situation as it develops, rather than acting according to plans made earlier". As you probably have guessed, this is a musical expression and can be traced back to the days before recording equipment was available to everyone.
Before the 1870s, when Thomas Edison invented the first sound recording and reproduction devices, musicians had to play music without reference to a written score. The way they had to learn a given piece of music was literally, playing by ear. The concept of ear to refer to musical talent was already in use since the 16th century, but the broader meaning we give today to the idiom play it by ear didn’t appear until the mid-19th century.
Steal your thunder

Don't you hate it when someone steals your thunder? But, did you ever stop to think what thunders have to do with upstaging someone and taking the credit properly belonging to someone else? Believe it or not, this is a story that dates back to the early 1700s, the golden era of Elizabethan theater.
The expression was first coined by the playwright and critic John Dennis, who invented a method of simulating the sound of thunder for his unsuccessful play Appius and Virginia. Shortly after, he attended a performance of Macbeth and, to his dismay, he discovered his groundbreaking sound effect was being used without his permission. According to documents of the time, Dennis wrote a review stating: "See what rascals they are. They will not run my play and yet they steal my thunder."
Back to square one

The meaning we give today to the expression back to square one is "to be back where one started with a project or plan". However, its literal meaning goes back to the glory days when television had not yet been invented and radio was the greatest form of entertainment.
In the 1930s, soccer and rugby fans could follow matches broadcasted by the BBC with the help of a printed plan of the pitch divided into squares. Commentators would murmur "Square five" or "Square three" as the ball moved about the field. Playing the ball back to square one meant losing maximum territorial advantage and, therefore, meant "back to the beginning".
The show must go on

Whenever something bad happens we use this phrase to give us courage, to remind us that we must carry on no matter what. According to Merriam-Webster Dictionary, the show must go on is "used to say that a performance, event, etc., must continue even though there are problems". Its origin is not entirely clear but its connection to the entertainment world is evident.
One theory indicates that the phrase was first coined in the 19th-century circuses, where incidents involving lost animals and performers suffering from injuries were commonplace. In these circles, the audience was more important than anything else, so regardless of what happened, the show would not be canceled. With time, the expression became widespread and is now used for any kind of situation, from theater and the hotel business to a birthday party.
