This Bag Contains ... Bag

This Bag Contains A Gun, A Bomb, A Very Large Knife And Loads Of Drugs The humour comes from the fact that the statement sounds serious and alarming at first, but then the punchline reveals that it's referring to a bag containing everyday items like a gun (a water gun), a bomb (a stink bomb or a balloon filled with air), a very large knife (a plastic toy knife), and loads of drugs (over-the-counter medication or candy). The unexpected twist generates laughter as it subverts the initial serious and ominous impression. It relies on the listener's assumption that it refers to dangerous items, only to reveal harmless or playful alternatives.
