THE PROP
Two slats, one bang
The Italian batacchio, or slap stick, has two thin wooden slats. It makes a loud smack with only a little force, so actors could hit each other again and again.
Date a gagThe joke was always in the sound.
Slapstick is named after a real prop: two thin slats of wood that clap loudly when they strike, while passing on very little force. From Italian comedy to the custard pie, the trick has stayed the same: make it look and sound far worse than it is.
- Big sound, small blow
- Action, not words
- One mishap leads to the next
- Four centuries of pratfalls
THE SHORT ANSWER
Named after a prop,
built on a trick.
A stick that claps instead of hurts.
A style that tells stories without words.
THE STAGE
Harlequin's magic bat
The V&A says the word also traces to 18th-century harlequinades, where Harlequin's wooden bat knocked down hinged flaps to change the scenery.
Two origin stories
THE PIE
From music hall to film
A 1904 music-hall sketch, Mumming Birds, featured the pie in the face. By 1927 a single film fight used some 3,000 pies.

FOUR THINGS TO WATCH FOR
It looks like chaos,
it is all planned.
Next time you watch an old comedy, look for the craft that has carried slapstick across four centuries.
Listen for the clap
The slap stick's whole point is sound: a loud smack that sells the blow while doing almost no harm.
Follow the chain of misses
In the 1927 pie fight each throw misses its target and hits someone new, who joins in. One mishap feeds the next.
Watch without words
Karno built sketches without dialogue in the 1890s to get round stage censorship. Good slapstick still works with the sound off.
Spot the old types
Commedia's masked stock characters, such as Harlequin and Pantalone, live on in pantomime and in the Punch of Punch and Judy.

Share of silent films believed lost
Silent films were routinely melted down after their runs. A 2013 Library of Congress study found that 75 percent are believed lost forever.
SILENT FILM SURVIVAL · LIBRARY OF CONGRESS
The pie fight itself was thought lost for decades: the second reel was rediscovered by a collector in 2015 and the film was pieced together from several archives.

TWO STORIES, ONE WORD
Whose bat
was it?
Most accounts trace the name to the batacchio of 16th-century Italian commedia dell'arte: two wooden slats that smack together on impact, among the earliest stage special effects along with the inflatable bladder.
The V&A tells a London version: in John Rich's 18th-century harlequinades, Harlequin's wooden bat changed the scenery by knocking down hinged flaps. Either way, the word for a whole style of comedy comes from a wooden bat.
In conversation
Questions people ask
Where does the word slapstick come from?
From a stage prop. The slap stick, or batacchio, is two thin wooden slats that make a loud slap when they strike another actor, with little force. The V&A also links the word to Harlequin's wooden bat in 18th-century pantomime.
Did a slapstick hurt?
Very little. Only a little force passes from the slats to the person struck, so actors could hit each other repeatedly with a big sound and very minor, if any, pain.
When did the pie in the face begin?
Fred Karno's 1904 music-hall sketch Mumming Birds, produced for the Hackney Empire in London, included the pie in the face gag among other new ideas.
How many pies were thrown in the famous 1927 pie fight?
The Library of Congress says some 3,000 pies were thrown in The Battle of the Century, a two-reel silent short whose second reel was missing for decades.
What is commedia dell'arte?
An early form of professional theatre from Italy, popular across Europe from the 16th to the 18th century, built on masked stock characters and improvised scenes with set comic routines called lazzi.
