* There's an episode of ''[[Battle of the Planets]]'' where the guy pounds the firing button with his fist, full strength. The missile practically explodes its way out of the launcher.
Line 24:
** The elevator example appears in the ''[[Hancock's Half Hour]]'' TV episode "The Lift".
** Busted by the [[MythBusters]] (elevator one).
* From ''[[Stargate Atlantis]]'', the last season, where an abandoned ship that autonomusly travels through parallel universes carrying the heros meets a universe full of hostile aliens, facing them to attack. Needless to say, Ronan is jamming on the rail gun button, then Seppard says,"Take it easy,

* [[Truth in Television]]. A common way of expressing frustration. Say you're in a hurry and you're trying to cross the street, and you pushed the button to cross, but the crosswalk light isn't changing. It's not uncommon in this circumstance to futilely press the button over and over. Similarly, if you click/double-click something on a computer and nothing happens, you'll be sorely tempted to do it again, even though this may just slow the action down further. I've also seen people playing fighting games start mashing the buttons harder as they get more desperate, even when it's just an ordinary digital button and they're only destroying the controller.▼
** Heh, the crosswalk thing: I press it repeatedly (generally four times, 'cuz I like the number 4) because I'm never sure that the first one took, and I don't want to be stuck waiting for a long time before I realize that I need to press it again. In some places, they've fixed this by having a place where you put your thumb (not a button, a scanner sort of thing), and when it registers that you're "pressing" it, it beeps. No more doubt.▼
** The "not sure it took" is the reason for ''most'' "press the button again" behaviors. That's why many elevator buttons (and a very few crosswalks) have an indicator light that says "Yes, I know you pushed me".▼
*** More a case of "''You'' know you pushed me," really.▼
*** All British pedestrian crossings have an indicator which lights when the button is pressed (on older versions, it's an illuminated WAIT sign, and on newer versions a red light). People still press the button repeatedly.▼
**** Irish crossings have the light too. But sometimes no light means "no signal" and a light means "signal received"; sometimes it's dim light: no signal, bright light: signal received; and sometimes it's permanently a dim light. So people press it over anyway.▼
** Some crosswalks at intersections that have been converted back to pure timer operation have their buttons disconnected, and pressing does nothing. People are already used to waiting, so nobody notices any difference.▼
* Pressing a road crossing button more times means that the time between the last button press and the change in lights is shorter...[[You Fail Logic Forever|I fail at logic]].▼
** Unless it thinks multiple people are waiting for the light and increases the urgency of the signal call.▼
* If your computer is going slowly, pressing buttons repeatedly will make it realize that you're impatient, and it will speed up. Doesn't everyone know this?▼
** On at least one system, this actually worked. The system was designed to give programs that interacted with the user a higher priority than background processes that didn't. Pressing random keys during a long calculation would make it treat the task as interactive, so the calculation finished sooner.▼
** A lot of PC GUI applications scroll this way. If you drag to select text or pixels, and your pointer leaves the scrollable part of the window, the will slowly start to scroll. Some apps scroll faster if the user moves the mouse because they scroll one unit per "event", and the mouse sends an event every time it has moved one or more pixels since the display was last updated.▼
** Some poorly-written applications on old cooperative-multitasked computers would do their processing only in response to OS messages. Meaning, the processing would go faster if you wiggled the mouse, or slammed on the keyboard, or otherwise did something to make the OS send more messages than usual. This could happen in Mac Classic applications, and 16-bit Windows applications.▼
* Some car remotes do react to multiple presses, for instance 3 presses of "lock" will start the engine.▼
* Most "close door" lift buttons aren't connected to anything. The lift doors don't close any quicker, but the user feels in control.▼
** They are, but unless you're in operator mode, they don't do much. In an elevator running in operator mode, the buttons give you total control. The doors will remain open until you select a floor or close them. You can even override the doors and leave them open as you travel.▼
* Many if not most auto-focus digital SLR cameras have a Pressure Sensitive Interface. Pressing the shutter release button partway causes the lens to focus, while pressing the button the rest of the way causes the camera to take the photo.▼

* In ''[[Bob and George]]'' the time travel suit is controlled by one button on the belt buckle. You have to practically type out a command in Morse Code with it to actually do anything. The duration and pressure of the press is important.
