Broomstick Quarterstaff

So our hero's weaponless and about to face a horde of Mooks. He looks around for anything that he can use in a pinch. He grabs the only thing available- a mop from the supply closet- and goes to town, using it as one would a Simple Staff.

Note that the title need not be taken literally. Anything vaguely cylindrical and tall as the character wielded as an Improvised Weapon falls under this; broomsticks and mop handles are simply the most iconic. Theoretically, this can be Truth in Television.

Sub-Trope of Improvised Weapon. Removing the head is optional based on the Sliding Scale of Seriousness Versus Silliness.

Video Games

 * In Final Fantasy VII, one of Cid's weapons is actually a mop (well, more like a push broom...). Other characters have similar weapons, which are rather powerful but lack materia slots. The best examples being an umbrella for Aeris, and baseball bat with a nail in it for Cloud.

 * This is Raine Sage's Lethal Joke Item weapon as well.

 * In Assassin's Creed Brotherhood, there is an achievement for killing someone using a broom. It is used the same way as a hammer. Brooms were first weaponisable back in Assassin's Creed II. Taken to absurd levels when you find out that it's possible to slit someone's throat using the broom, with the same sound effects of a regular bladed weapon.
 * Buffy the Vampire Slayer for the X Box. Stuck without a weapon? Look for a broom or a mop (or just kick a chair in half).

(Considering her son's experiments, a wise precaution...)
 * In The Boondocks, Huey snaps the head of a broom off with a kick and uses the handle to subdue the theater security, but he doesn't fare as well against Uncle Ruckus' unforseen nunchaku expertise.

Truth In Television

 * There actually are weapon forms that exist for a Boat oar in Shaolin Kenpo for this very reason.
 * Actually trying this with a broom handle, however, is more likely to get your enemy annoyed if you smack them with it: it's not heavy enough. Use it for blocking instead.
 * Leave a boy alone with a broom long enough, and this will be invoked.
