Farts on Fire

""In China it's considered perfectly good manners to talk with your mouth full and to burp after your meal. Farting seems to vary according to the situation and your current company, so ask ahead of time. Lighting the fart is frowned upon in almost all provinces.""

Flatulence is set aflame.

This does work in Real Life, though not always, and not very impressively. Despite the fact that it is Truth in Television, Don't Try This At Home.

Science fact: farts are, essentially, just the body expelling methane. Methane also flees quickly. Timing is required. Rather than the huge flame you see in certain cartoons, it'll be a tiny blink-and-you'll-miss-it flame. Don't ask us how we know.

Fartillery is this taken to its illogical extreme.

Anime and Manga

 * Tremors 3 takes this trope to the extreme. The Assblasters are capable of propelling themselves to flight at high altitudes by igniting their own farts. One even used this technique to try and burn through Burt's bomb shelter.
 * In the 1993 Live-Action film of Dennis The Menace, when Dennis is (unknowingly) held captive by a burglar, and he is accidentally handcuffed by Dennis, Dennis accidentally drops the release keys into a cooking pot of beans, since "Food is not wasted" Dennis force-feeds him the entire pot making him to fart near the fire causing a big flame.

Literature

 * Dave Barry's column "Apocalypse Cow" tells of a university professor who set fire to methane emitted by cows for classroom demonstration purposes.
 * Not played for laughs: In Stephen King's novel IT, a fart-lighting scene leads to a homosexual encounter between two of the Bad kids. It's one of the most suspenseful scenes in the book, because the whole thing is witnessed by one of the Good kids.
 * Happens in Lois McMaster Bujold's The Vor Game, where the main character, dubbed the camp idiot for a (rigged) accident with a piece of major equipment, is relieved when the title is taken over by a couple of new recruits who set their tent on fire lighting "fart flares."

 * The MythBusters tried it (in a segment they could not air in the USA but did overseas...and the US execs finally relented for the anniversary "Top 25" special). Although the flatulence was flammable, the flame itself was fairly unimpressive and it didn't remove the smell at all.
 * In The Young Ones episode Cash, Vyvyan thinks he's pregnant, backed up by his rapidly expanding gut. Turns out it was just gas. Right after it's released someone(I think Rik), lights a cigar, and blows the house up.

 * Stephen Colbert attempted this to demonstrate how to fix the oil spill in the gulf. It didn't go so well and we instead got some Relax-O-Vision as the stagehands put him out. On the bright side, he doesn't need to worry about that waxing appointment anymore.
 * A segment of a bizarre German game show featured a sort of "word of the day." The clue was as follows: A woman in lingerie bends over, and the camera does a close-up of her butt. A flame is brought near it, and the result is something like a Bunsen burner. (The word of the day was, of course, "gas.")
 * Happened in the christmas episode of Bottom. Richie had meade a special christmas snack containing year-old sprouts, as well as other rather nasty and spicy ingrediants. The guys all passed out and when they woke up they were randomly spouting and fire from their asses.
 * In the I'm in The Band episode "Don't Date the Principal's Daughter", Burger does this  (because he accidentally discovered earlier that pulling the wrong finger will result in a burp when it's Burger), but fails hilariously

Newspaper Comics

 * The Far Side may have been Getting Crap Past the Radar by showing the fantastic variation of young dragons lighting their sneezes.

At one point, flames shoot out of his butt, propelling the gurney some twenty feet, with Beavis screaming in pain. It's never adequately explained what led up to this, leaving it to the viewer's imagination.
