A quest called Rifle the Bodies in Borean Tundra is a quest where the player must right click on the corpses of mages to receive a bag filled with a random assortment of grey items or a quest item that the player needs to complete the quest chain.
When I was doing this quest on my alt, I spam-clicked one of the corpses and multiple bags spawned for me with grey items.
The grey items vendor for 10-20 silver, which is nothing huge, but moving back and forth between Star's Rest and these corpses could actually be a decent way to make cash, especially if someone found a way to automate it.
The problem is, it didn't work on every single corpse. For every seven corpses I tried, only one of them actually allowed me to spawn 5 or more bags.
I used a lagging tool to lag WoW and spam my right mouse button on the corpse. I had a greater success rate using that method instead.
