For my 4E group, the contents of the bag of holding they have just taken from the lair of the beholder.
This beholder had probably just recently taken out a group of adventurers, as the contents of its bag of holding contains several items that are quite useful for our heroes.
They have found 4 potions of healing and a variety of alchemical concoctions. There is a Cask of Liquid Gold, Gloves of Recovery, Claw Gloves, and a Map of Unseen Lands. There is also a set of musical instruments (a djimbe drum, a flute, a horn, a lute, and a lyre) that are all wildly out of tune but when played together sound quite strangely in-tune somehow, and several pieces of artwork. There are twelve statues and twenty-two paintings of mind-flayers dressed up as circus clowns, and they are all clearly the work of the same (mad) artist.
