An.actual thing that happened in one of my campaigns (as a VERY young and immature DM, 2e AD&D era):

>used a "Trifling Treasures" random table to put seemingly-inocuous, random items in the pockets of slain monsters
>one of the PCs loots a rubber duck from a slain goblin or something, and keeps it
>[Several Levels Later]
>PCs need to get aboard a ship at anchor off off the coast (to kill some guy and reclaim some thing), but have no boat
>PC pulls out his rubber duck (plan.jpg)
>Casts Enlarge Object (2e version)
>Rubber duck is now 30' in size
>Druid uses Gust of Wind, etc to steer the duck alongside the ship, under cover of darkness
>PC casts Levitate on said rubber duck boat
>Rubber duck ascends to deck level; PCs lay siege to the vessel and slaughter its crew, retrieve the thing
