How Is That Even Possible?

A Stock Phrase that is commonly used as a Lampshade Hanging of those occasions when the laws of physics (and other scientific laws) are blatantly defied. This is sometimes caused by Achievements in Ignorance, when the impossible thing only occurs because the person involved has no idea that what they are doing is supposed to be impossible.

Often Played for Laughs, this phrase can be used to tell the audience that the strange or unusual occurrences going on aren't the norm for the world in which the story is taking place. It can also be used as part of the Rule of Scary for the same reason.

On occasion, this trope will be accompanied by an explanation of how the strange occurrence is impossible. The creators will do use this to avert the Did Not Do the Research trope and demonstrate that they did their homework.

Compare and contrast with Fridge Logic.

Live Action TV
"Spock: Captain, you don't seem to understand. It did not function, but it must function. McCoy: Nothing could go wrong, Captain. It should work. Spock: A scientific fact. But if the tranquillizer does not function, which is clearly impossible, then a radical alteration of our thought patterns must be in order."
 * In an early Sesame Street sketch, Ernie poured himself a glass of milk while hanging upside down, ignoring Bert's warnings that the milk would spill.

""What I hate about my life... Part of what I hate about my life is that it is working.""
 * Subverted in Eight Bit Theater. Fighter claims that gravity had been slain (since Black Mage had saved them by cushioning their falling airship with a large explosion as it crash landed), which would allow them to fly...and to everyone's amazement, takes off. Then it turns out Sarda the Sage decided the best way to bring them to him would be to fly them in at just that moment.
 * This is generally BlackMage's reaction to the improbable things his much-hated teammates do. By the time the Light Warriors reach the Temple of Fiends again, he's stopped complaining.


 * Sarda also invokes this (using a Flat What) when Ranger dual-wields his dual-wield.
 * Happens to the word in this Questionable Content strip, when an AI appears to be drunk.

Web Original
"Church: Poor Jimmy was the last one to go. Tex walked up to him, pulled Jimmy's skull right out of his head and beat him to death with it. Tucker: Wait a second... how do you beat someone to death with their own skull? That doesn't seem physically possible. Church: That's exactly what Jimmy kept screaming. (cut to Tex, in black armor, beating Jimmy to death with his own skull) Jimmy: This doesn't seem physically possible!"
 * From Red vs. Blue:

"Goku: "Oh, all right. I promise I will absolutely not click-brrrrrrr *long inhale* rrrrrrrrr" King Kai: "He hung up on me! How did he even do that?""

Western Animation
"Zoidberg: My home, it burned down! How could this have happened? Hermes: That's a very good question! Bender: [picking up his still-lit cigar from the underwater ruins] So that's where I left my cigar! Hermes: That just raises further questions!"
 * The Trope Namer was Camp Lazlo, specifically the episode where they tried to sell expired, uncanned beans. A man was walking towards the stand... and then floated into midair, drifted right over the stand, and then floated back onto the street and continued walking. This prompted Raj to ask how that was even possible.
 * Futurama: In one episode, Bender's arms fall off. A moment later we see the arms, in closeup, pick up and reattach each other. Fry is just as baffled as the audience.
 * Another Futurama example was in a scene taking place deep beneath the ocean...

"Kuzco: No, it's impossible! How did you get back here before us? Yzma: "Ah..." [looks confused] How did we, Kronk? Kronk: Well, ya got me. [pulls down a chart displaying the progress of the previous chase] By all accounts, it doesn't make sense."
 * From The Emperors New Groove:


 * During the Justice League episode "Hereafter", the Flash is almost fried by enemy lightning. Wonder Woman saves him by deflecting the lightning with her metal bracelets. Flash's response? "There are so many reasons why that shouldn't have worked."
 * In a Road Runner cartoon, Wile E. Coyote runs off a cliff while in pursuit of the Road Runner who, it turns out, is standing just off the edge of the cliff in mid-air. The bedraggled Coyote looks up from the bottom of the canyon at the Road Runner and holds up a sign commenting that what the Road Runner is doing defies the laws of gravity. The Road Runner responds by holding up his own sign saying it doesn't matter because he's never studied law.
 * In "The PTA Disbands" episode of The Simpsons, Homer gets upset at Lisa for making a working perpetual motion machine because it violates the laws of physics. ("In this house, we obey the laws of thermodynamics!")
 * 1973-74 Superfriends episode "The Watermen". The title characters are trying to refuel their starship by extracting silicon from sea water. This causes the sea water to immediately turn into red tide, which is impossible: red tide is caused by microorganisms. An oceanographer named Professor Matey points out several times that the red tide is not acting normally.
