Smoke bomb
The smoke bomb was created in 1987 by Batman. He shared his technology with a secret group of outcast ninjas known as magicians. After quitting his day job as a crime-fighting lunatic dressed as a bat, Bruce Wayne gave the blueprints for his little ball that would release smoke that you couldn't get high off, to the United States Government.
Poof! And he's gone[edit]
When the Batman first invented the smoke bomb, his intentions were to smoke it like a ciggie or as the Americans say, a cigarette. This proved difficult, so instead he used the smoke to cover his escape while he would bash up criminals during the hours of midnight to 4am.
It's magic, or something[edit]
Magicians would use smoke bombs on stage to confuse their audience and reappear on a different part of the stage. Until 1994, smoke bombs were seen as actual, real magic until people came to the conclusion that Batman also uses them and he's just a regular guy that dresses up like it's halloween every night. After this bombshell, ticket prices dropped for magic shows and many Magicians were forced into the sex industry, many dying within a year from Aids and other STI's.
Military usage[edit]
It is unknown what the United States army use the smoke bombs for as every time someone gets close to the truth, soldiers would throw a smoke bomb down and disappear before they can be asked. It is speculated that the smoke bombs are used to hide tanks but this was debunked by common sense as if there is random smoke somewhere, it has to be hiding something, right?
Smoking deaths[edit]
There have been several deaths related to the usage of smoke bombs as idiots would try to inhale the smoke to get high. Instead, they are treated to the gates of hell. The official name of dying this way is listed as 'second hand smoke' which led to the name of the hand grenade.
