Is This Thing On?

Bob the rock star is ready to wow the crowd with his hip brand of radical rap-rock-metal fusion. He calmly walks onto the stage. The crowd remains in an eager silence. He takes slow, echoing steps towards his personal, Jimi Hendrix signed microphone. His hand reaches out to grasp it. A light but dramatic cough, and... "Hey, Is This Thing On?" *tap tap tap* "Testing, testing, 1-2-3...".

Okay, so it's rarely that dramatic. But 9 times out of 10, you can bet any character, no matter how experienced with electrical sound equipment, WILL utter this phrase. You've probably Seen It a Million Times, probably even in real life. For some reason the microphone will always feedback for a moment. Unfortunately, because of a case of TV Never Lies, many people will often do this in Real Life, thinking this is the normal way to test a microphone. Doing so actually damages the microphone, and the AV technicians running the show will probably get really frustrated at you. If feedback DOES occur, the AV will become even more frustrated. Despite this fact, all forms of media still use this trope, misleading the common people to think that it is the proper way to check a mic.

Not to be confused with Is This Thing Still On?, though the two are vaguely similar.

Comedy
"Bill Bailey: A medieval roadie? Ah, one do I say, one do I say, one do I say, one do I say then surely two should follow, two should follow, two should follow, two should follow."
 * Stock covering line for a comedian who tells a joke at which no-one laughs.
 * Parodied by Zack Galifianakis, playing a stand-up comic from the 1700s. "Is this thing on?...What is this thing?"
 * In Bill Bailey's Part Troll tour, he mentions how in one review he was described as looking like "a medieval roadie":


 * Averted in CrapShots #25. Graham tests the microphone, but does not tap it.

Comic Strips

 * In one Far Side comic, captioned "Testing whether fish have feelings", two scientists have one microphone in a fishbowl inhabited by a single goldfish and another one being held by one of the scientists. The scientist begins to yell insults at the fish, only to ask if the mic is on when he doesn't get a response.

Fan Works
""Is this thing on? (coughs noisily) You are now thinking about what Zarbon did to you while you were unconscious. Have fun with that.""
 * in Dragon Ball Abridged, while mentally contacting Vegeta.

Films -- Animation

 * The Incredibles has it in its initial interview to Mr. Incredible.
 * In Home on the Range, show cow Maggie says this line and blows at her cow bell.

Films -- Live-Action

 * Said in the The Prowler when the supervising teacher tells the partygoers that there is a prowler on the grounds and everyone should stay inside.

Literature

 * Discworld
 * Played with in the novel Thud: an ancient recording of a historic dwarven leader begins with a couple of loud knocking noises, followed by "Art thys thyng workyng?"
 * In Soul Music, Asphalt the roadie says "One two. One. One. One two." prior to the concert at The Cavern, but doesn't know why.
 * In one Ciaphas Cain novel, an out-of-touch, confused planetary governor practices a speech... only to learn that the camera was in fact on the whole time.

Live-Action TV

 * Doctor Who: The Doctor does this with his camera when recording his instructions for Martha in Human Nature.
 * In one of the last episodes of I Love Lucy, Fred installs an intercom between his guest house and the Ricardo's main house. Lucy tests it with the "Testing 1,2,3" method.

Music
"I sit alone in my four cornered room, starin' at candles... Oh that shit is on? heh. Let me drop some shit like this here"
 * Geto Boys -- "My minds Plain' Tricks on Me"

 * The Eminem Show album ends with a skit. During the skit Ken Kaniff taps the microphone and says "Erm... izzis thing on...?"
 * At the start of "The Real Sugar Baby" (a cover of Eminem's "The Real Slim Shady", only with a female singer and with "sugar baby" instead of "slim shady") the singer goes into the mic at the start; "Hello, is this thing on?"
 * The Shellac song, "The End of Radio", repeats this phrase many times. Which is especially surreal when you consider that band leader Steve Albini is a professional recording engineer. "This... microphone... turns sound into electricity! Can you hear me now?!"
 * Lady Sovereign begins "A Little Bit of Shhh" with this phrase.
 * Zach De La Rocha of Rage Against the Machine would usually open concerts by shouting "one, two"
 * Less Than Jake has a song with this trope as its name. It uses the phrase to represent loneliness and watching the world leave you behind.

Video Games
"Wesker: Is this thing on? Excella, I told you I hate AT&T! [sigh] Greetings, you have reached Albert Wesker's... celulate device. I'm currently away on business-- business that does not concern you. If Chris has given you this number I'll deal with you shortly. If you're calling to confirm the date of launch for the final phase of... the plan, please dial 01-800- [background noise] Excella, do not touch that! [more noise] Goddamnit, woman!"
 * In Dead to Rights, the objective of one of the levels is to stop a member of a corrupt SWAT-style unit from calling his boss. During the level the guy constantly repeats "Come in, hey Dick you copy! This stupid... What's the damn frequency?"

 * Used in the start of the opening theme for Sid the Science Kid.

Real Life

 * Being an experienced professional doesn't mean that you don't do it -- it means that you spend an hour doing it before the show starts to make sure the levels are correct.
 * Some professionals don't, however. Techs often use tongue-twisters, poems, songs and even a grocery list to sound check to ensure a broad range of vowel and consonant sounds are properly equalized. Tapping the mic, however, is frowned upon.
 * And even that doesn't foretell if the thing's actually going to work. Someone who's had a mic fail on them even after all this testing will still perform this ritual to make sure the thing's working.
 * Tapping the mic damages the thing. That is why it is frowned upon. It is also really frustrating for the AV when the people using the mic to tap the thing, not trusting the AV that it is on and working.
 * Surprisingly frustrating when working smaller venues. During sound checks, inexperienced singers will literally just say "check check, one two" and leave it at that as a result of this trope. In reality it takes a minute or two to properly EQ each microphone, and a few mumbled words are of no use to man nor beast. Many will also need to be given a specific topic to talk about, as they're often unwilling to sing a'capella in front of their mates and blowing their cool.
 * The trope is justified however, as both "testing" and "one two" feature harsh syllables (Two), plosives (WUH-ne) and sibilance (teSSSting), the three fiddliest aspects of speech to amplify. Once you've got these three sorted, the rest is easy.
 * Some replace "toast" for "testing", which serves much the same purpose. There's also usually at least one smart arse who goes for "testes". It's neither as funny nor as original as you think it is, but it tends to break up the monotony.
 * Reputedly happened to a priest at the beginning of Eucharist. "And He took the bread, praised God and said: Is This Thing On?"
 * At one point in his Presidency Ronald Reagan was asked to talk into a mic for a sound level and turned the trope Up to Eleven by saying "Negotiations with the Soviet Union have failed, we begin bombing in ten minutes." Needless to say the Russians were not amused.
