A notorious joke weapon responsible for the failure of countless murder and suicide attempts. When the trigger is pulled, the gun barrel emits a large flag saying "BANG!"
If the person holding the gun assumed the gun was real, expect an Oh, Crap
The title is a take on BFG
- Used often by The Joker. You can never be sure what kind of gun The Joker is pointing at you until he pulls the trigger. And even if it's a BANG Flag Gun, you can't be sure if he's not going to kill you with it anyway.
- One comic had him using the BANG Flag Gun to kill a henchman.◊ First the flag popped out, causing the henchman to think the Joker was playing a prank on him. Then the flag got fired like a speargun, killing the henchman.
- He does the same thing in the Batman Beyond movie, Return of the Joker. He is Hoist by His Own Petard with it, causing him to mutter, "That's not funny."
- Variation in The Killing Joke: The Joker finds he is out of bullets when his gun produces a flag saying "CLICK CLICK CLICK".
- At the end of Andrew Helfer's prose story "On the Wire" from The Further Adventures of the Joker anthology, the Joker, despondent over having failed to drive a lonely woman on a chat line to suicide, glumly decides there's only one thing to do. He points a gun at his head and pulls the trigger, releasing a BANG flag. That cheers him up.
- He also uses it as a weapon in an issue of Birds of Prey, where he shows it off to an unruly henchman, holds it right up to their eye and says "Wanna see?" before pulling the trigger.
- He uses one for his Fatality Move in Mortal Kombat vs. DC Universe. He whips out the gun and fires it at his victim, causing them to jump and then act exasperated. He then pulls a real gun while the victim is reacting and shoots them with it.
- When MAD did a parody of Joseph Wambaugh's cop novel The New Centurions, one of the cops shot himself just before his scheduled retirement. Another cop said it must be because he felt he'd have nothing to live for after retiring, but it turned out he'd just mistakenly used a real pistol instead of the flag gun.
- Another one from MAD had a world courtesy of Don Martin, where these guns were used instead of real guns. Highlights include a silenced version (the flag says "thwip" in really small letters), a Chinese version, (the flag's "bang" is written in Chinese), and an aircraft-mounted version (multiple bang flags)
- On a Deadpool cover by Dave Johnson, Deadpool points an autoloader at the reader with a Bang flag coming out of it. In the background, a number of Faceless Goons lie on the floor, Bang flags embedded in their heads.
- New Warriors. A BANG Flag Gun was used by the prosecutor to send the telekinetic Vance Astrovik to prison. His grabbing the smoke -of- the gun with his mind was used to prove he didn't have to be fatally damaging in defense from his father's abuse. The fact the prosecuter made everyone think she was trying to kill Vance didn't seem to actually matter to the judge. Prison ensued.
- The Invisibles: Used to kill one of the Big Bads in a variant of Your Mind Makes It Real.
- The Joker uses this on Vicki Vale in the 1989 Batman film, naturally. Which elicited one of Kim Basinger's zillion screams in that film.
- The Mask scares off some mooks with two handfuls of guns (all of which turn out to be of these type), while doing a Dirty Harry impersonation to boot.
- Diamonds Are Forever: In a deleted scene available on the CD, Mr. Wint and Mr. Kidd kill Shady Tree with a BANG Flag Gun that also shoots a real bullet.
: Shady Tree... Shady, we just adored your act. Mr. Kidd
: What taste... style. Mr. Wint
: And we have a few suggestions. Shady Tree
: Critics and material I don't need; I haven't changed my act in 40 years! [Mr. Kidd pulls out a water gun flower] Mr. Kidd
: Ah, but this one's surefire... Shady Tree
: That's the oldest Godda-- Mr. Wint
: And this one... will kill you. [Mr. Wint puts a gun to Tree's head; the BANG Flag Gun pops out reading BANG! You're Dead!] Shady Tree
: Come on, fellas. The popping gun and the squirting flower routine? You gotta be kidding m-- [Mr. Wint empties a live bullet into Tree's brain] Mr. Kidd
: Two's company, Mr. Wint... Mr. Wint
: And Tree's a crowd, Mr. Kidd. [James Bond continues toward Tree's dressing room as Albert R. Saxby intercepts Wint and Kidd on departure] Albert R. Saxby
: Hold it! Don't go in there. We didn't get the real diamonds, so we need Tree... alive. Mr. Kidd
: That's most annoying...

- I Love Lucy features one in its fourth episode, "Lucy Thinks Ricky Is Trying to Murder Her". Ricky is preparing stuff for one of his shows and one of the items is a "Bang" flag gun that Lucy thinks is a real gun, finally culminating in Ricky "shooting" Lucy, showing her that it is a prop.
- One episode of Hogan's Heroes had the guys sabotage a flak battery and topped it off with BANG flags when the Nazis tried to bring down the Allied planes.
- In The Drew Carey Show Mr. Wick decides to get an extra laugh out of firing Johnson. He hands him a crossbow and says that he's fired unless Johnson can shoot an apple off of his head. When Johnson pulls the trigger, a flag that says "You're Fired" drops down from the arrow. When Johnson shifts the the crossbow in his hand to be able to read the flag better he hits the trigger again firing the arrow and hitting Mr. Wick in the um... goodybag.

- How about a Gunbrella? (Sadly, it may be out of production now.)
- In the musical Celebration, Mr. Rich tries to kill himself by shooting himself in the head with a pistol, which produces a "BANG" flag when he pulls the trigger.

- The Sheriff Mecha in MechQuest has a pistol that fires real bullets but sometimes shoots a flag out instead.
- The flag gun is even used as the Joker's fatality move in Mortal Kombat vs. DC Universe...except it's subverted when he then drops it and pulls out a real gun.
- Used in Day Of The Tentacle by a suicidal hotel guest who puts it to his head and pulls the trigger (the flag comes shooting harmlessly out his ear). Could be horrific under the right circumstances, but it's all Played for Laughs.
- Joker again: In the final cutscene of Lego Batman, Joker's thrown into jail again and looks ready to shoot himself in despair before we find it's one of these joke guns. (You read that right: Joker put a gun to his head in a Lego game.)

- Plok gets one in his game in the form of the cowboy powerup outfit, found exactly once. As could be expected, it's largely useless, having a pitifully short range and a very slow firing rate. The primary reason the powerup is where it is in the first place is virtue of the fact that collecting any powerup outfit restores Plok's limbs if they're currently on a hanger somewhere else.
- One type of enemy uses these in one of the stages in World of Illusion. They do, however, cause real damage.
- If you fail Wonder-Green's intro quick-time event in The Wonderful 101, his rifle pops a flag decorated with a film clapper board with "CUT!" scrawled on it before he unceremoniously falls like a rock.
