A performance or performer that evokes so much applause from the audience that the show is temporarily interrupted.
For obvious reasons, this is primarily a theater and live performance trope, as static audiences can't exactly rise up and give a standing ovation in a movie theater. It can still be parodied in that context, though, as pretty much everyone knows the basic idea behind a show stopper. Indeed, such meta-awareness dates to early 20th century film, if not earlier - it's an essential part of the live performance genre. Sometimes the script might actually call for the actors to nod toward the fourth wall in thanks.
A sillier variation, often enforced by a Laugh Track
, is where a single character, simply by appearing on the stage, evokes such thunderous applause from the audience that everyone has to take a break before any lines can actually be said. Note that in original theater this was still part of the point. Back then it was called a clap trap — a part of a play or a musical performance designed to evoke applause, with a pause in the action to accommodate it. Since then, the phrase has been used to mean nonsense.
This is the supertrope to Epic Rocking
- Whose Line Is It Anyway?, being performed in front of live audiences, often relies on at least one sketch being this in each performance. There's also a special game called "Show Stopping Number", which parodies this trope.
- Although the most epic one was probably Sid Caesar's guest appearance.
- Or Richard Simmons'.
- One game of "Superheroes" had Wayne Brady as "Show-Stopping Number Boy."
- The Weekenders made fun of this trope:
Carver: "Why can't we help you? I mean, sure, Tino is pretty clueless, but I stopped the show with my act last year."
Lor: "You knocked over a light and set the stage on fire."
Carver: "Which stopped the show."
- Austin Powers does it all the time. After doing or saying something cool, Austin turns to the audience and says, "Oh, thank you," in reply to the applause he expects.
- One time on WWE Smackdown, when Hulk Hogan returned to WWE, his applause lasted a TV segment (approximately 15 minutes). When they came back from commercial, the crowd was still applauding — but since it wasn't broadcast live, it could have been only a short time after they "went to break" that they stopped. (Or conversely, it could have gone on for even longer.)
- Kramer on Seinfeld. They actually had to ask the audience to tone down the clapping, because it was ruining the show's pacing.
- In Home Improvement, every time a funny is made, the Reaction Shot of (usually) a confused Tim lasts for several seconds before the laughter dies down.
- Steve Urkel from Family Matters would often evoke this response upon entering the scene.
- Jazz from The Fresh Prince of Bel-Air also had this effect when he'd drop in to the Banks' house, ironically more so after he started appearing less.
- Lampshaded in Forever Amber when the actors pause to acknowledge the entrance of King Charles II.
- "The Parson's Bride" segment of 1936's Show Boat, in which all the actors acknowledge the audience at their entrances and exits.
- Red Dwarf has the line-delayed-by-laughter version: the Polymorph takes the form of Lister's boxer shorts, which start shrinking after he puts them on. Kryten (who has a vacuum cleaner attachment plugged into his groin socket) is desperately trying to remove them when Rimmer walks in. There's a very long pause before Rimmer makes a comment, because Chris Barrie had to wait for the audience's laughter to subside enough to be heard.
- Parodied in a sketch on The Carol Burnett Show where she and Harvey Korman played famous stage actors. They would enter the scene within the scene and get tons of applause, which would always stop as soon as they acknowledged it and started to bow, creating many uncomfortable pauses.
- In later seasons of Married... with Children, the entrance of nearly any major character was met with cheers and hoots from the studio audience, forcing the cast to pause for a second before continuing the scene.
- In a segment of The Chaser's War on Everything, Chas "tests" whether botox/fake-tans/dyed-hair will increase his attractiveness (or rather, make him hot like Daniel Craig). He does this to only one half of his body and face, leaving the other half untouched. The utter ridiculousness of his appearance leads to continued laughter from the studio audience even when Andrew attempts to move on to the next segment of the show, eventually causing Andrew to start laughing as well and have to restart the segments introduction.

- ONION BUBS! ONIOOON BUUUUUBS!!
- The three-part DCLAU crossover "That's So Suite Life of Hannah Montana" had applause play whenever a character entered another's show.
- "It's now time to play the game called Mornington Crescent."
- Johnny Carson's appearance on The Late Show with David Letterman.
- In stage musicals, a powerful enough song can generally be considered a showstopper - "Defying Gravity" from Wicked is one such example, and "One Day More" from ''Les MisÚrables" is another.
- In opera, in addition to songs, single notes can be showstoppers. One prime example is the second act of Tosca, which has one showstopping aria (Vissi d'arte) quickly followed by Cavaradossi's famous outcry of "Vittoria! Vittoria!". If done well, the audience will cry "Bravo!" at this point and interrupt the show.
- Parodied in a commercial for The Opie And Anthony Show, with Jim Norton making the big entrance.
- Two in 1776:
- "The Lees of Old Virginia" is deliberately written to be as big and hammy as possible to carry the audience through the next half-hour, which is devoid of songs.
- "Molasses to Rum" is a much darker version that has Edward Rutledge damning the North by acting out a slave auction, to which slaves have been brought by New England ships. He only stops when a Northern man begs for mercy, and the whole Congress is left stunned and silent.
- The Lion King musical has the songs "Circle Of Life" and "He Lives In You".
- In "The Talent Show" on the PBS version of The Berenstain Bears, Brother Bear is assigned as the talent scout for the school talent show. He finds a number of good acts, but is desperate to find his "showstopper," the big act that will bring down the house. His showstopper turns out to be the local "gang" leader / bully bear Too Tall, who has a surprisingly tender and compelling singing voice.
- During his Season 2 guest run on Friends, Tom Selleck garnered such an endless ovation every time on set that they wound up shooting his scenes without an audience just so they could actually finish filming the episodes.
- During the 2016 Grammys Hamilton performance, they deliberately added in several extra lines of silence after Lin-Manuel Miranda first sings the line "Alexander Hamilton" to account for the applause, but the applause was so strong that the next line ("My name is Alexander Hamilton") was still drowned out anyway. Compare this to the first performance of the song, back in 2009 at the White House, where the same line also created a strong response from the audience - but of confused laughter. How things have changed!
