Wacky Weapon Ideas

I am making a mod fully of funny, weird weapons. Anyone with Ideas please put them in the comments.For reference I mean things like a gun that shoots charged creepers or a sword which covers the floor in slippery banana blocks (both of which are in the mod already). Keep in mind that I don't want to spend hours on a weapon(unless its really funny).
